Return Value:

Returns the square root of argument.


public class Math {

 public static void main(String[] args) {

  double a = Math.sqrt(9); //calculates square root of 9
  double b = Math.sqrt(2456.7); //calculates square root of 2456.7
  double c = Math.sqrt(-4568); //calculates square root of -4568

  System.out.println("Math Square root value :" + a);
  System.out.println("Math Square root value :" + b);
  System.out.println("Math Square root value :" + c);

Nice to see here a Java section…

By the way, I tried to run the code, but not worked until I changed the class name to Main.
