Below is my code:

public class Practice_3 {
   public static void main(String[] args) {
        //Question-1:
                //****
                //***
                //**
                //*
        String str ="*";
        int n =4;
        for(int i=n; i>0; i--){
            for (int j=i; j<=i;j--){
                System.out.print(str);
            }
            System.out.print("n");
        }
    }
}

Whenever , i try to run it , it kept on running infinelty.
