Java program to take a number as input and calculate the square root of given number

Following program shows you how to take a number as input and calculate the square root of given number.
In this program we get input from user and calculate square root using Math.sqrt() method

import java.util.Scanner;

public class BasicMath9 {

	public static void main(String[] args) {

		System.out.println("Enter a number:");

		double input;

		Scanner in = new Scanner(System.in);
		input = in.nextFloat();

		double result = Math.sqrt(input);

		System.out.println("Input: " + input);
		System.out.println("Square root of " + input + " is: " + result);

	}

}

Output:

Enter a number:
64
Input: 64.0
Square root of 64.0 is: 8.0
