Question

write a program in java to input a number and print the square of the digit of the number​

Answer 1

Answer:

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 1

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
