Square Root Method of Math Class in Java

Introduction

Returns the square root of the argument in Java.

square root:
a number that produces a specified quantity when multiplied by itself.

7 is a square root of 49

double sqrt(double d)

Sample Code

public class main {
    public static void main (String [] args) {

        //Returns the square root of the argument.
        System.out.println("Math.sqrt(100) = " + Math.sqrt(100));
        System.out.println("Math.sqrt(81) = " + Math.sqrt(81));
        System.out.println("Math.sqrt(64) = " + Math.sqrt(64));
        System.out.println("Math.sqrt(49) = " + Math.sqrt(49));
        System.out.println("Math.sqrt(36) = " + Math.sqrt(36));
        System.out.println("Math.sqrt(25) = " + Math.sqrt(25));
        System.out.println("Math.sqrt(16) = " + Math.sqrt(16));
        System.out.println("Math.sqrt(9) = " + Math.sqrt(9));
        System.out.println("Math.sqrt(4) = " + Math.sqrt(4));
        System.out.println("Math.sqrt(1) = " + Math.sqrt(1));
        System.out.println("Math.sqrt(0) = " + Math.sqrt(0));
    }
}

Output from The Program

Math.sqrt(100) = 10.0
Math.sqrt(81) = 9.0
Math.sqrt(64) = 8.0
Math.sqrt(49) = 7.0
Math.sqrt(36) = 6.0
Math.sqrt(25) = 5.0
Math.sqrt(16) = 4.0
Math.sqrt(9) = 3.0
Math.sqrt(4) = 2.0
Math.sqrt(1) = 1.0
Math.sqrt(0) = 0.0
