## Solution:

Welcome mate.

Let’s come to the point. You can square a number in a couple of ways. The easiest way to square a number is multiplying with itself.  Another way is to call a method named math.pow

Let’s see how to do it using math.pow

``````import java.util.*;
public class Square{

public static void main(String args[]){

Scanner sc=new Scanner(System.in);
int number;
System.out.print("Enter a number: ");
num=sc.nextInt();
System.out.println("Square of "+ number + " is: "+ Math.pow(number, 2));

}

}``````

Using a method where we will multiply the number with itself

``````import java.util.Scanner;
public class SquareNum{

public static void main(String [] args){

Scanner sc = new Scanner(System.in);
System.out.print("Please enter a number: ");
int num = sc.nextInt();
System.out.println("Your squared number is: " + square(num));

}

//Here is our method to get the square

public static int square(int num){

return num * num;

}

} ``````
