//Newtocoding
//Java program for pythagorean triple for loop
/*5.21 (Pythagorean Triples) A right triangle can have sides that are all integers.  The set of three integer values for the sides of a right triangle is called a Pythagorean triple.  These three sides must satisfy the relationship that the sum of the squares of two of the sides is equal to the square of the hypotenuse.  Find all Pythagorean triples for side l, side2, and the hypotenuse all no larger than 500.  Use a triple-nested for-loop that tries all possibilities.  This is an example of "brute force" computing.  You will learn in more advanced computer science courses that there are large numbers of interesting problems for which there is no known algorithmic approach other than using sheer brute force

I need to use 3 for loops and prompt for input and display
import java.util.Scanner;

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

Scanner number = new Scanner(System.in);

System.out.print("Enter length of side A of triangle's sides from 1 to 1000: ");
sideA = number.nextInt();

System.out.print("Enter length of side B of triangle's sides from 1 to 1000: ");
sideB = number.nextInt();
System.out.print("Enter length of side H of triangle's sides from 1 to 1000: ");
sideH = number.nextInt();

int sideA=0;
int sideB=0;
int sideH=0;
static int max = 1000;
if (sideA>max; sideB>max;sideH>max) {
System.out.println("You entered an invalid number");

String biggestNumber=""+ biggestNumber;
biggestNumberString=biggestNumberString.length();
