    else if(!isOpen) 

    {

      numAttempts++;

    if(numAttempts == 3) 

    {

      System.out.println("ALARM");//prints alarm when the combo is incorrect 3 times

    } 

  } 

}

as of right now, my program only gives me two attempts and then is gives me an output of false when I want it to say ALARM. Edit the code if you like and comment exactly what I should do. I also have some more debugging that would be nice if I got some help with so that I can have a fully functional program

You aren't getting two attempts right now. What you are seeing currently is the output from this set of code:

System.out.println("Enter key");

int key1 = Integer.parseInt(objReader.readLine()); // set to 111  



System.out.println("Enter key2");

int key2 = Integer.parseInt(objReader.readLine()); // set to 222



Lock lock1 = new Lock (key1);

Lock lock2 = new Lock (key2);



System.out.println(lock1.isOpen); // prints false

You currently only have one open attempt for each lock. If you add more open attempts like:

lock1.open(111); // opens lock1

lock2.open(222); // opens lock2

lock1.open(111); // opens lock1

lock2.open(222); // opens lock2

lock1.open(111); // opens lock1

lock2.open(222); // opens lock2

It will print out your expected behaviour

If I understand it right, you want to the Locks to be OPEN by default? If so, just change to this:

Lock(int key) 

{

    isOpen = true; // < true as default (instead of false)

    this.key = key;

} 

This leads to the following output:

• true


• Opened


• Opened
