A good answer might be:

No, not in any one run of the program. Like a combination lock, any wrong number will cause the lock to fail to open.

User Input

Here is the program with some additional details filled in, and some details that you are to fill in: 

_______________
class ComboLock
{
  public static void main ( String[] args ) _______________
  {
    int lockFirst = 6, lockSecond = 12, lockThird = 30;  // The combination
    int numb;   // a user-entered number

    BufferedReader stdin = new BufferedReader( 
        new InputStreamReader( System.in ) );
    String input;

    boolean correct = true;

    //First Number
    System.out.println("Enter first number: ");
    input = stdin.readLine();
    numb  = Integer.parseInt( input );

    if ( _______________ )
      
      correct = _______________ ;

    //Second Number

    //Third Number

    //Result
    if ( correct )
      System.out.println("Lock opens");
    else
      System.out.println("Lock does not open");
  }
}
