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

They keyword this refers to the instance of the class. In a static context, you have no instance, therefore you can't refer it.
