What is the difference between having something static or not.

Question

pls reply with static and without static

Answer 1

static methods or variables can be called without creating any instance of that class.

For example imagine a class named Calculator and its static method Sum()
here.....
Calculator c= new Calculator();
System.out.print(c.Sum(20,25));

we can do this if the Sum method is static..

System.out.print(Calculator.Sum(20,25));

You see I could use the Sum method without creating any instance of Calculator class.

Hope it helped... 😃😃

Answer 2
