Can someone help me figure out the error in this problem of finding the gap of 100 consecutive composite number between 2 primes

Question

The code is in java .Help find out the error

import java.util.List; import java.util.ArrayList; public class Prime100 { private List<Long> primes = new ArrayList<>(); private long targetGap; public Prime100(long targetGap) { this.targetGap = targetGap; primes.add(2L); primes.add(3L); } boolean isPrime(long n) { boolean ok = true; for(long p: primes) { if(p * p > n) { break; } if(n % p == 0) { ok = false; break; } } if(ok) { long lastPrime = primes.get(primes.size() - 1); long gap = n - lastPrime; if(gap == targetGap) { System.out.println(lastPrime + " -> " + n + ": gap = " + gap); } primes.add(n); } return ok; } public static void main(String[] args) { Prime100 primeChecker = new Prime100(102); long n = 5; while(true) { primeChecker.isPrime(n++); } } }

Answer 1

Yeah yeah it is correct i entered somewrong punctuation bdw thank for looking over 💕💕

Answer 2

Is there a bug? In eclipse it works without any problems. The only thing is, it's hard to read. I just formatted the code for easy reading. Maybe someone else will find the error. But the search for prime numbers is correct.

package soloHelp;

import java.util.ArrayList;
import java.util.List;

public class Prime100 {
private List<Long> primes = new ArrayList<>();
private long targetGap;

public Prime100(long targetGap) {
this.targetGap = targetGap;
primes.add(2L);
primes.add(3L);
}

boolean isPrime(long n) {
boolean ok = true;
for (long p : primes) {
if (p * p > n) {
break;
}
if (n % p == 0) {
ok = false;
break;
}
}
if (ok) {
long lastPrime = primes.get(primes.size() - 1);
long gap = n - lastPrime;

if (gap == targetGap) {
System.out.println(lastPrime + " -> " + n + ": gap = " + gap);
}
primes.add(n);
}
return ok;
}

public static void main(String[] args) {
Prime100 primeChecker = new Prime100(100);
long n = 5;
while (true) {
primeChecker.isPrime(n++);
}
}
}
