Recall the Pythagorean Theorem says that if a; b are the lengths of two edges of a right triangle, then the length of the hypotenuse c is given by c2 = a2 + b2: Write a Java application which prompts the user to enter the lengths of two edges of a right triangle and then computes the length of the hypotenuse. 
import java.util.Scanner;
public class Hypotenuse
{
public static void main(String[] args)
{
Scanner scan = new Scanner(System.in);
double a,b,c;
System.out.print("Enter the lengths of two sides: ");
a = scan.nextDouble();
b = scan.nextDouble();
c = Math.sqrt(a*a + b*b);
System.out.println("The hypotenuse has length " + c);
}
}

Answer the following question.
What is the output of the following code fragment?

int x = 1;
while (x<5)
{
System.out.println(x);
if (x==3) x++;
else x = x+2;
