Java Program To Calculate Square Root Of Any Number - Java Program Example

Here we will see a java  program For calculate square root of any number we multiply number.

When run this java  program then compiler ask input a number for calculate square root that number which imputed by user. For eg - you enter 9, than compiler show squire root after compile 3 on screen.

Program Code  

 package com.androidpro.in;



import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStreamReader;

import java.util.Scanner;



public class Main {



    public static void main(String[] args) throws IOException

    {



        int number = 0;

        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));



        System.out.println("Enter a number to \ncalculate square root of any number");



        String line = br.readLine();



        try

        {

            number = Integer.parseInt(line);

        }

        catch (NumberFormatException exception)

        {

            System.out.println("Please enter a valid number");

        }

        double squareRoot = Math.sqrt(number);

        System.out.println("Square root of a number " + number + "=" + squareRoot);

    }





}

 

Output

Enter a number to

calculate square root of any number

44

Square root of a number 44=6.6332495807108
