Data types in Java

A variable provides us with named storage that our programs can manipulate. Each variable in Java has a specific type, which determines the size and layout of the variable’s memory; the range of values that can be stored within that memory; and the set of operations that can be applied to the variable.

Variable in Java is a data container that saves the data values during Java program execution . Every variable is assigned a data type that designates the type and quantity of value it can hold. Variable is a memory location name of the data.

There are three different types of variables a class can have in Java are local variables, instance variables, and class/static variables .
