Program:

            /* ............... START ............... */
                
public class JavaVariableExample {

	int instance_varialbe = 100; // instance variable
	static int val = 100;// static variable

	void getValue() {
		int local_Variable = 90;// local variable
	}

}
                /* ............... END ............... */
        

Notes:

• Variable is a name of memory location that can contain a data value.
• A variable has a data type.
• There are three types of variables in java: local, instance and static.
• Local Variable : A variable which is declared inside the method is called local variable.
• Instance Variable : A variable which is declared inside the class but outside the method, is called instance variable .
• Static variable : A variable that is declared as static is called static variable. Memory allocation for such variables only happens once when the class is loaded in the memory.
