正確打印Java中的循環

Question

我一直在這個程序上工作幾個小時，代碼工作正常，但我似乎無法讓它正確打印出來，它應該只是爲每個值打印一次，如：

數：6

分頻器：2 3 6 1

素：不是素數

Output

可以在任何一個幫助？截圖附上。謝謝！

public static void main(String[] args) { 

    Random randomNums = new Random(); 

    int count; 

    for (int i = 1; i <= 37; i++) { 

     count = randomNums.nextInt(100) + 1; 
     System.out.println("number " + count); 

    for (int b = 1; b<=count; b++) { 
     if (count % b == 0) { 
      System.out.println("dividers " + b); 
     } 

    } 
    for (int a = 2; a< count; a++) { 
     if (count % a == 0) { 
      System.out.println("is not prime"); 
     } 
     if (count % a != 0) { 
      System.out.println("is prime"); 
     } 
     }  
    }  
    }  
}

嘗試寫驗證碼：

public static void main(String[] args) { 

    Random randomNums = new Random(); 

    int count; 

    for (int i = 1; i <= 37; i++) { 

     count = randomNums.nextInt(100) + 1; 
     System.out.println("number " + count); 
    String dividers = ""; 
    for (int b = 1; b<=count; b++) { 
     if (count % b == 0) { 
      dividers += b.toString() +" "; 
     } 

    } 
    // control the print beside loop 
    System.out.println("dividers " + dividers); 
    // add the control for whether prime 
    bool prime = true; 
    for (int a = 2; a< count; a++) { 
     if (count % a == 0) { 
      System.out.println("prime : is not prime"); 
      // add the control for skip loop 
      prime = false; 
      break; 
     } 
    } 
    if(prime){ 
    System.out.println("prime : is prime"); 
    }  
    }  
}  

}

根據你的邏輯，我猜，如果你決定，一些是不一個素數，那麼這是最後的結果，

所以

boolean isPrime = true; 
String dividers = ""; 
for (int a = 2; a< count; a++) { 
    if (count % a == 0) { 
     isPrime = false; 
     dividers += a+" "; 
    } 
} 

if (isPrime) { 
    System.out.println ("is Prime"); 
} else { 
    System.out.println ("dividers "+dividers); 
    System.out.println ("is not Prime"); 
}
