this: Cannot use this in static context

Question

Can you please help me with below code. The error is: \"Cannot use This in a static context\"

public class Sample2 {
    /**
     * @param a         


        

Answer 1

In java you can not use this in static methods (static context).

Static methods do not point to any instance of the enclosing class.

A static method cannot refer to “this” or “super” keywords in anyway

Refer official docs on this keyword
