pls give me hints so I could clear this question...... this program....... what to do in it.
package com.codegym.task.task01.task0127;
/*
Square of a number
*/
public class Solution {
public static void main(String[] args) {
int a=5;
System.out.println("the square of 5 is = "+a*a);
}
public static int sqr(int a) {
return a * a;
}
}
