Calling static method from non static method in java

• Static means class level and non static means object level.
• Non static variable gets memory in each in every object dynamically.
• Static variables are not part of object and while class loading itself all static variables gets memory.
• Like static variables we have static methods. Without creating object we can access static methods.
• Static methods are class level. and We can still access static methods in side non static methods.
• We can call static methods without using object also by using class name.
• And the answer to the question of  "is it possible to call static methods from non static methods in java" is yes.
• If we are calling a static method from non static methods means calling a single common method using unique object of class which is possible. 

Program #1: Java example program to call static method from non static method.

1. package com.instanceofjava.staticinterviewquestions;
2. public class StaticMethodDemo {
3.  
4. void nonStaticMethod(){
5.         
6.         System.out.println("Hi i am non static method");
7.         staticMethod();
8.  }
9.     
10.  public static void staticMethod(){
11.         
12.         System.out.println("Hi i am static method");
13.   }
14.     
15.  public static void main(String[] args) {
16.         StaticMethodDemo obj= new StaticMethodDemo();
17.         
18.         obj.nonStaticMethod();
19.  
20.     }
21.  
22. }

 Output:

1. Hi i am non static method
2. Hi i am static method

• In the above program we have created object of the class and called a non static method on that object and in side non static method called a static method.
• So it is always possible to access static variables and static methods in side non static methods
