Java help...Checkboxes

**university123** · 10-25-2010, 04:09 AM

Here is my new code that I changed! Can I just add the "tie" scenarios in with the other statement that I will post? Is there a way to do that, and if so could someone help me out with that?

Java Code:

        String setText = null;

     if (p1 == p2)
     {
         if (p1 == p3) 
             setText = "It's a tie between pieces 1,2 and 3";
          else 
             setText = "It's a tie between pieces 1 and 2";
         }
      else if (p1 == p3) 
         setText = "It's a tie between pieces 1 and 3";
      else if (p3 == p2) 
         setText = "It's a tie between pieces 2 and 3";
        
     
     
     if (setText == null) 
        {
     
           String winMsg = null;   
        
     if (p1 > p2 && p1 > p3) {
	     winMsg = "Piece 1 is the winner";
	     box1.setSelected(true);
	     
     } else if (p2 > p1 && p2 > p3) {
	     winMsg = "Piece 2 is the winner";
	     box2.setSelected(true);
	     
     } else if (p3 > p1 && p3 > p2) {
	     winMsg = "Piece 3 is the winner";
	     box3.setSelected(true);
     }
     
     result.setText(winMsg);
     {

I'm not quite sure I understand what you mean. You want to merge the tie scenarios into the winning scenario statements?

**university123** · 10-25-2010, 06:18 AM

Well I tried what you did, and it woked, but then my statements that just said "piece 1 is the winner" would not show up and none of the check boxes worked! So i'm not quite sure what happened?

Here is my code so you see what I mean!!

Java Code:

This is what your code looks like now for decided the winner, there is a problem with all of them like it:

Java Code:

if(p1>p3)
{  
     result.setText("Piece 1 is the winner"); // Here is the problem line
     box1.setSelected(true);
}

After this code executes you use the following statement that is overriding the code above so that null is being displayed:

Java Code:

result.setText(setText);

Inside the "if" statement, why not just assign setText the output string instead of printing to the screen at that specific time. And to add check boxes to the tie scenarios just use the same code you used for the winning pieces except check both boxes.

**university123** · 10-25-2010, 06:42 AM

So is there a way I can fix this...I am so confused and this project is due later today, so I am straped for time right now. I just need all the statements to work along with the checkboxes. I know it can't be too hard but for some reason I am struggling with this!! here is what I have for my code RIGHT NOW!

Java Code:

You didn't change anything, no one will help if you show no effort to even change anything when given help.

**university123** · 10-25-2010, 06:48 AM

I understand that I need to change it, but that's where I am stuck. I have been at this for days and tried a countless number of ways at yet have come up with the correct way!!

**joshdgreen** · 10-25-2010, 06:54 AM

I told you the line you need to change, make this:

Java Code:

result.setText("Piece 1 is the winner");

Look like this:

Java Code:

setText = "It's a tie between pieces 1,2 and 3";

Also, the formatting of your code is very confusing. You should work on that and maybe walk through your code line by line and do a hand check on paper and pencil as to what things are doing and why they are doing them. And it's not our fault your code is due and you aren't finished.

**university123** · 10-25-2010, 07:04 AM

I never said it's your fault that the code is due. I have a full time job, and I also go to school full time, so I have lots of priorities to take care of. I was just asking for some simple help. That is all!

**university123** · 10-25-2010, 07:39 AM

I have this for my "tie" statements but it's not working. Can anybody help

Java Code:

       String winMsg = null;        
        
       if (p1 > p2 && p1 > p3) {
           winMsg = "Piece 1 is the winner";  
           box1.setSelected(true);
           
           if (p1 == p2 && p2 == p3) { 
           winMsg = "It's a tie between pieces 1, 2, 3";  
           box1.setSelected(true);  
           box2.setSelected(true);  
           box3.setSelected(true);  

 } 
  
       
    } else if (p2 > p1 && p2 > p3) {  
           winMsg = "Piece 2 is the winner";  
           box2.setSelected(true);  
           
           if (p1 == p2)
           winMsg = "It's a tie between piece 1 and 2";
           box1.setSelected(true);
           box2.setSelected(true);
           
           if (p2 == p3)
           winMsg = "It's a tie between piece 2 and 3";
           box2.setSelected(true);
           box3.setSelected(true);

    } else if (p3 > p1 && p3 > p2) {  
           winMsg = "Piece 3 is the winner";  
           box3.setSelected(true);  
           
           if (p1 == p3)
           winMsg = "It's a tie between piece 1 and 3";

You're missing brackets {}.

**al_Marshy_1981** · 10-25-2010, 12:39 PM

Try making it less confusing
1. Check for an individual win
2. Check for tie between two pieces
3. Check for tie between all pieces
Use separate if's for all of the above; makes code less messy

im going to give a sample of checking for tie between two pieces:
*note the check that the tied pieces are greater than the other piece...

Java Code:

if(p3==p2 && p3>p1){
