static vs instance methods js code example

Example: static method vs instance 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.
3) Static and non-static variables both can be accessed in instance methods.
4) For example: public void msg() {
...}.
