    Default What's wrong with my code? Are there any errors? Is the idea right? Please helpThanks

    //I want to know if this program is right. The program uses loops to find the first 400 primes.
    class Primes {
    public static void main(String[] arguments) {
    int counTer2 = 0;
    primeLoop:
    while (counTer2 < 401) {
    for (int prime = 2; prime<prime+1; prime++) {
    for (int number = 1;number <prime+1; number++) {
    int counter = 0
    if (prime%number == 0)
    counter = counter + 1;
    }
    if (counter == 2)
    System.out.println("#:" + prime);
    counTer2 = counTer2 + 1;
    }
    if (counter2 == 401)
    break primeLoop;
    }
    }
    }

    Does the code compile? Is the output that which you would expect?

    As a side note, consider using code tags when posting your code as this makes it much easier to read. For instance:

    class Primes {
    public static void main(String[] arguments) {
        int counTer2 = 0;  
        primeLoop:
        while (counTer2 < 401) {
          for (int prime = 2; prime<prime+1; prime++) {
             for (int number = 1;number <prime+1; number++) {
                int counter = 0    
                if (prime%number == 0)
                counter = counter + 1;
                }
             if (counter == 2)
                 System.out.println("#:" + prime);
                 counTer2 = counTer2 + 1;
          }
          if (counter2 == 401)
          break primeLoop; 
        }
      }
    }

    To use these, you would wrap your code with these tags: [code=java] [/code]
