# Prime Triplet in Java

A prime triplet is a collection of three prime numbers in the form (p, p + 2, p + 6) or (p, p + 4, p + 6).

Write a program in Java to display all the possible prime triplets in the range m and n, where the value of m and n are entered by the user.

Example:
INPUT:
M = 1
N = 20
OUTPUT:
5, 7, 11
7, 11, 13
11, 13, 17
13, 17, 19

``````import java.io.*;
class PrimeTriplet{
public static void main(String args[])throws IOException{
System.out.print("M = ");
System.out.print("N = ");
for(int i = m; i <= n; i++){
int p1 = i;
int p2 = i + 2;
int p3 = i + 6;
if(p2 > n || p3 > n)
break;
if(isPrime(p1) && isPrime(p2) && isPrime(p3))
System.out.println(p1 + ", " + p2 + ", " + p3);
p1 = i;
p2 = i + 4;
p3 = i + 6;
if(p2 > n || p3 > n)
break;
if(isPrime(p1) && isPrime(p2) && isPrime(p3))
System.out.println(p1 + ", " + p2 + ", " + p3);
}
}
public static boolean isPrime(int n){
int f = 0;
for(int i = 1; i <= n; i++)
if(n % i == 0)
f++;
return f == 2;
}
}``````

Sir,a program is given which states that:
WAP in Java to display all Pythagorean triplets from m to n(both m and n are inclusive)(m<n)(m and n are to be accepted by the user)
Hint:6,8,10 are said to be pythagorean triplet
(6^2+8^2=10^2)
m and n are to be accepted as positive integers

Here is the Pythagorean Triple Program.
