Bounded Type Parameter in Java Generics

In Java Generics, a situation can arise where we need to restrict or bound an object type to specific types only in order to narrow down the acceptable types supported in the type parameter. For instance, a method that deals with numbers, should accept Number and its sub-classes. Bounded Types: The concept of limiting type parameter upto certain type is known as bounded types. In this, extends…

What Is The Purpose Of Generics In Java ?

The purpose of generics in Java is to offer type safety and to overcome type casting problem. Type safety can be defined as the concept of holding a correct data by a variable with respect to its type. It means, if a variable is capable of holding string type then it should not allow other types. It prevents type errors, making the compiler efficient to validate types at compile time. The Generic…

What is Generics in Java with Example ?

Generic programming is a way of creating classes, interfaces, and methods to work with various data types. It provides the flexibility to write a feature that is independent of the specific datatypes. In simple words, it allows us to create a class, interface, or method that accepts various datatypes automatically in the parameterized way. Therefore, Generics concept is also termed as…
