Question

For every natural number m>1; 2m, m² − 1 and m² + 1 form a Pythagorean triplet. Write a program to input the value of 'm' through console to display a 'Pythagorean Triplet'. 

Sample Input: 3

Then 2m = 6, m² - 1 = 8 and m² + 1 = 10 

Thus 6, 8, 10 form a 'Pythagorean Triplet'. 

Answer 1

import java.util.*;
public class Q2
{public static void main(String args[])
{Scanner in = new Scanner(System.in); 
int m, x, y, z; 
System.out.println("Enter a natural number");
m = in.nextlnt(); 
x = 2 * m;
y = m * m - 1;
z = m * m + 1; 
System.out.println(x + "," + y + " and " + z + " are Pythagorean triplets");
