Types and Features Arrays are of two types- String and Car. These are capable of containing respective objects. The objects that are stored in these containers are generally put to use in various calculations or for the purpose of referencing. These data structures may have grades that are capable of getting the same referenced or averaged. These are basically data structures that hold similar type of objects. Declaration of array calls for allocation of memory space for particular value types. The length of these structures should be specified as it remains constant at the time of creation of the same. An item in an array is termed as an element which can be accessed by its particular numerical index. An element of an array which in turn is itself an array is termed as a subarray. These are capable of having single or double dimensions. These data structures are similar to the list of items or columns of a spreadsheet. For each row they have specific position numbers. The position numbers in this case starts with zero and then follows sequence while going up. Thus each position in it holds a value. The numerical index which is basically a non-negative value that corresponds to the location of an element is used to access that particular array element. The very first index value is zero; simultaneously the fifth element in the array can be accessed through the index having the value four. Programming in Java with the help of Arrays: Programming with the help of arrays in Java has a number of characteristics and features that demand careful attention of the programmers before starting to work with it. Length of the Array: The size of the array is fixed once it is created. One can refer to the length in the program with the help of the code a.length. Setting of the values of arrays at the time of compilation: Listing the values between the curly braces, separating them by putting a comma in between the two, when there is a small number of literal values that one intends to put in these data structures, initializes it. Zero-based Indexing: Usually the first element in an array is referred to as a[0], the second is referred as a[1] and so on. This convention that has starting the index with zero has certain advantages and has emerged as the most popular convention used in majority of the modern day programming languages. Setting the value of arrays at run time: It is a more complex situation when the programmer wishes to go for computing the values that are to be stored in the data structures at run time. Representation of Memory: The process of memory allocation is Java takes place when the user uses new for creating these structures. Eventually Java reserves some space for it in memory as well as initializes the values for the same. Bounds Checking: One needs to be careful while programming with these structures. Using legal indices is the responsibility of the programmer while accessing array elements. Benefits of Using Arrays: There are several advantages of using arrays in Java. First of all, a specific element within a large group of the same can be easily accessed with the help of the index of the element and name of the structure. Furthermore, arrays prove to be useful at the time of execution of calculations within loop. It is the most effective and efficient data structure that can be used to store and access a sequence of objects. These structures have the option to be used for the implementation of data structures like stacks, trees, linked lists, queues, graphs, etc. Making use of a single name, these structures are used for representing numerous data items of same type. Arrays prove to be highly efficient with respect to the memory footprint and processing time. Limitation in using Arrays: There are certain limitations with respect to the use of arrays in Java and storing of elements. The user should be aware of the exact number of elements that are to be stored in one array in advance. Since it is a static structure, the size of arrays is fixed. As a result the memory allocated to the array cannot be thus decreased or increased. With the size being fixed, allocation of memory exceeding the requirement will result in sheer wastage of the memory space. Again allocating memory that is less as compared to the required space, there will be a problem. Insertions as well as deletions with respect to the array elements are not only time consuming but also too difficult and complex activities as the elements are generally stored in memory locations that are consecutive to each other.

Five Widely Used Java Frameworks and Their Usage in Programming 1) Play: As a lightweight framework, Play is hugely popular among Java programmers due to its speed, performance and scalability. It allows developers to use both Java and Scala programming languages. The developers familiar with Scala can start using the open source frameworks without putting any extra effort. However, Play comes with a simple and intuitive interface. It further enables developers to compile their code frequently. They can simply hit the refresh button to see the changes. Play also comes with several testing tools to assess the application. However, Play does not support version compatibility. So Play 2 is not compatible with Play 1. 2) Grails: Despite being a hugely popular open source framework, Grails is built upon a number of frameworks like Spring, Hibernate and GROMS. Many developers rely on Grails due to its support for Enterprise Java Beans (EJB). The EJB support makes it easier for developers to start development without configuring the XML. Grails further comes with loads of readymade modules and speedy development features. It allows users to carry out unit testing, while integrating Grail with other testing frameworks. 3) Spring: As a powerful Java framework, Spring is used widely by programmers to creating testable and high performing applications. Spring is designed with features required for taking care of the application’s petty usability features. So it becomes easier for developers to concentrate on the project’s main features, without writing additional code for these petty features. Spring further allows developers to integrate several components seamlessly to resolve intricate problems. Spring also supports cloud computing, along with both RDMS and NoSQL databases. It also comes with features to make the application secure and compatible with mobile devices. 4) Struts: The open source web development framework is developed by Apache Foundation. Struts is hugely popular among Java programmers due to its JSP custom tag libraries and collection of utilities. Despite complementing the needs of complex web development projects, the core architecture of Struts is both simple and extendible. Struts 2 also comes with a set of features that are identical to the features of Spring MVC. But Struts is much faster than Springs MVC, while providing better UI support. Despite being there in the market since some time, Struts 2 is still hugely popular among Java programmers. 5) Eclipse: Despite being used widely by Java programmers, Eclipse still supports multiple languages. The open source integrated development environment (IDE) helps programmers in creating rich client side applications. Further, the application developed using Eclipse can run smoothly on multiple platforms including Windows, Linux and Safari. Its updated features can also be used by programmers for deploying desktop application. So the programmers can use Eclipse for both developing desktop as well as rich internet applications. While using Eclipse, the programmers also have option to write code in Java, C, C++, Ruby, COBOL or SCALA. At the same time, they can easily extend the framework by using several plug-ins. On the whole, each developer has option to choose from a wide range of Java frameworks. But the role of individual frameworks varies in Java programming due to their varying features. So the programmers must evaluate these frameworks according to specific requirements of their project.

1) The rise of various alternative languages to fame. 2) Scalability of Multi-Core processors or platforms. 3) Return of fat clientele. Let us look into the issue in fairly details. The Rise of Various Alternative Languages to Fame The last few years have seen the introduction of several other languages that the developers have really fallen for. These alternative languages can again be split into two categories or groups – languages those are designed to run on Java Virtual Machines or JVMs like Scala, Groovy etc, and languages those which do not run on JVMs. A considerable number of languages fall within the former bracket. These languages that are compatible to JVMs are not mutually exclusive to Java and hence, when seen from a certain perspective, they only make the JVMs stronger as well as more robust when it comes to developing software. Again, speaking about languages like Groovy, the developers need to be a bit more expressive, so as to enjoy the maximum advantage it offers. However, for that what Java needs is an updated library with some value added features so far as performance is concerned to enjoy the benefit of the developers’ doubt. Again, as these alternative languages come up with certain features that Java does not offer, the newer versions of Java need to include those features in order to compete. Here, it will not be impractical to mention that the J EE5, EE6 and J 8 Lamdas have come up with value added features that are similar to those found in those alternative languages. Hence, that brings us back to the bottom line ‘J’ needed some face lifting to retain its pertinence in the web development fraternity – something it has already done. It can also be mentioned that Java is not actually kicked out by these languages, but their presence has only prompted Java to take a new guard to ensure its safety. Scalability of the multi core platforms or processors That JVM runs on single core is already known. That was possible for the spawn threads that were released by the first edition of Java. However, the limitation of these threads is that they do not execute in parallel, and compel the CPU to switch between one thread to another very fast, so as to create an impression that they are executing in parallel, though they are not. Here comes JStack that denotes whether these threads are eligible to run or are actually running. On the other hand, truly executing thread parallelism is possible only with the multi core CPUs and hence, JVMs need to have the capacity to decide when it needs to execute the parallelism of threads. In order to get a better parallelism, what Java needed was a unique feature, which it came up with in its 7th avatar. That feature, the Fork/Join Framework uses double queue and ‘work stealing’ for increasing parallelism. Return of fat clientele The factor that acts as a boon for Java is that its scripts are actually harder to understand than what people actually think them to be. Naturally, it takes a lot of thinking as well as conceptualization for the developers to have a total grip on the language. However, there are quite a number of clients who would like to have people with an excellent understanding of Java in their team, even if it costs them more. Java is still popular with these clients, particularly when it comes to developing single page applications, for which the developers need to know how actually the web works. Hence, it can well be mentioned that though ‘J’ had a torrid time, it is far from getting obsolete. Perhaps, it will be more apt to mention here that these rough times have only toughened the language, as it has introduced itself with more vigor and robustness to cope with the changing times and demands.

5 Significant Differences between Java Stacks and Python 1) Nature of the Programming Language: As a programming language, Java is typed statically. Thus, Java can be used as a low-level implementation language. If you decide to use Java Stacks, there are options to choose from several JVM languages. These languages can be further combined to complement a number of JVM languages including Groovy, JRuby, Scala and Clojure. On the other hand, as a dynamic typing language Python can be used effectively as a glue language. If you are looking for an interpreted programming language, it is advisable to choose Python. 2) Object Oriented: Many reports have highlighted that Java can run faster than Python. But Java required programmers to define the type of each variable. Further, they have to define a class before writing any code. The code also needs to be complied by invoking compiler, before running it. But Python allows programmers to run the code directly without declaring any data type. Also, the programmers have option to combine both imperative and object-oriented programming. 3) Cleaner Code: Many developers rely on Python as a dynamic programming language to quickly complete the same coding tasks. Thus, the programming language makes developer more productive. Like other dynamic programming languages, Python can also be used for prototyping and testing at a rapid pace. As Python allows programmers to prototype and test rapidly, they can create a much higher number of prototypes in the amount of time required to create a single prototype with Java Stacks. The developers also have option to integrate Python with existing environments by using specialized tools like IronPython (for .Net) and Jython (for Java). 4) Performance: As noted earlier, Python runs slower than Java Stacks. Unlike java, the dynamic languages do not run closely to the processor. So these languages fail to deliver adequate level of speed. However, the performance of Python can be easily enhanced by using multi-core processors. A number of large enterprises are already using powerful processors to smoothly run high-performance trading applications developed with Python. However, you have to incur some additional expenses to create the environment to run Python applications faster. 5) Security: Both Python and Java Stacks come with several security features. The dynamic languages are also not less secure than Java or .NET. However, a number of reports have highlighted loads of Java vulnerabilities. Some of these Java vulnerabilities are also critical, and have affected thousand of Java applications. However, the instances of Python vulnerability are limited. So developers rely on dynamic languages like Python to deliver secure enterprise applications. As Python is an open source programming language, they have further option to avail the assistance of a large community of developers. While comparing Java Stacks and Python, you must remember the nature and needs of your project. It is also a great idea to evaluate the pros and cons of each option based on the requirements of your project. The initial research will help you in choosing the right option for completing the project without putting any extra time and effort.
