reference static method from instance java code example

Example 1: how to call a static method in java

class scratch{
	public static hey(){
		System.out.println("Hey");
    }
	public static void main(String[] args){
		hey();
        //print Hey to the console
    }

Example 2: instance method and static method

static or class method
1) A method that is declared as static is known as the static method
2) We don't need to create the objects to call the static methods
3) Non-static (instance) members cannot be accessed in static context 
(static method, static block and static nested class) directly.
4) For example: public static int cube(int n){
return n*n*n*; (multiply *) }

Instance method
1) A method that is not declared as static is known as the instance method.
2) The object is required to call the instance method.
