A Pythagorean Triple is a set of positive integers, a, b and c that fits the rule: a^2 + b^2 = c^2
So if the three numbers are 3, 4, and 5.
3^2 + 4^2 = 5^2
9 + 16 = 25
so it is a Pythagorean Triple

Write a program to check if the given numbers are Pythagorean triplets or not.
import java.io.*; 
class pythagoras 
{ 
public static void main()throws IOException 
 { 
    BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); 
    System.out.println("Enter the base"); 
    int base=Integer.parseInt(br.readLine()); 
    System.out.println("Enter the height"); 
    int height=Integer.parseInt(br.readLine()); 
    System.out.println("Enter the hypotenuse"); 
    int hypo=Integer.parseInt(br.readLine()); 
    if(hypo*hypo==base*base+height*height) 
    { 
     System.out.println("A Pythagorean Triple"); 
    } 
    else 
    { 
     System.out.println("Not a Pythagorean Triple"); 
    } 
 } 
}

Output:
Enter the base
2
Enter the height
4
Enter the hypotenuse
5
Not a Pythagorean Triple
