Types of Variables in Java
Now let us discuss different types of variables which are listed as follows:
1.Local Variables
-A variable defined within a block or method or constructor is called a local variable.
2.Instance Variables
-Instance variables are non-static variables and are declared in a class outside any method, constructor, or block.
3.Static Variables
-Static variables are also known as Class variables.
* These variables are declared similarly as instance variables. The difference is that static variables are declared using the static keyword within a class outside any method constructor or block.
