Java program to find the square root of a number

Hi friends, today I have written a post on how to write a Java program to find the square root of a number.

What is Square Root?

Square root 'p' of a number 'q' is a number such that p² = q.

    
     import java.util.*;
class Sqroot
{
    public static void main(String args[])
    {
        Scanner in = new Scanner(System.in);
        int a;
        double sroot;
        System.out.println("Enter a number");
        a=in.nextInt();
        sroot=Math.sqrt(a);
        System.out.println("The square root of the number is "+sroot);
    }
}
    
  

Output:

Enter a number

4

The square root of the number is 2.0
