Java Program to Find Square of a Number

Write a Java Program to find Square of a Number using methods with example.

Java Program to Find Square of a Number Example 1

This Java program allows the user to enter an integer value. Then this Java program calculates the square of that number using Arithmetic Operator.

// Java Program to Find Square of a Number
import java.util.Scanner;

public class SquareofNumber {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int number, square;
		sc = new Scanner(System.in);
		
		System.out.print(" Please Enter any Number : ");
		number = sc.nextInt();		
		
		square = number * number;
		
		System.out.println("\n The Square of a Given Number  " + number + "  =  " + square);
	}
}

Java Program to Find Square of a Number Example 2

This Java program is the same as above. But this time, we are creating a separate Java method to calculate the square of that number.

// Java Program to Find Square of a Number
import java.util.Scanner;

public class SquareofNumber1 {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int number, square;
		sc = new Scanner(System.in);
		
		System.out.print(" Please Enter any Number : ");
		number = sc.nextInt();	
	
		// Calling below static method calsqaure
		square = calsquare(number);
		
		System.out.println("\n The Square of a Given Number  " + number + "  =  " + square);
	}
	
	public static int calsquare(int num)
	{
		return num * num;
	}
}

Java square of a number output

 Please Enter any Number : 64

 The Square of a Given Number  64  =  4096
