#java variable types

Java is a statically-typed language, which means that variables have to be declared before they can be used. Java is also a strongly typed language because all the data types are already defined in it. variable is a container that stores a value. Before using a variable, it has to be given some value. The value stored in a variable can be changed during the execution of the program. Every variable in Java has a specific type, which determines the size and layout of the variable's memory.
