void getdata() — to accept three numbers
void findprint() — to check and display whether the numbers are Pythagorean Triplets or not.
Answer
import java.util.Scanner;
public class Triplet
{
private int a;
private int b;
private int c;
public void getdata() {
Scanner in = new Scanner(System.in);
System.out.print("Enter a: ");
a = in.nextInt();
System.out.print("Enter b: ");
b = in.nextInt();
System.out.print("Enter c: ");
c = in.nextInt();
}
public void findprint() {
if ((Math.pow(a, 2) + Math.pow(b, 2)) == Math.pow(c, 2)
|| (Math.pow(b, 2) + Math.pow(c, 2)) == Math.pow(a, 2)
|| (Math.pow(a, 2) + Math.pow(c, 2)) == Math.pow(b, 2))
System.out.print("Numbers are Pythagorean Triplets");
else
System.out.print("Numbers are not Pythagorean Triplets");
}
