problem with indexOf() and contains()

May 20th, 2009
Hello,
I am having problems with indexOf() and contains() they work if I put letters in the code to test, but I want it to test what the user enters. And that is not working. The user enters a letter into a JTextField, and I am storing that word to a string variable, and then testing that variable in contains() and indexOf() but that is always returning the number that means the letter isn't in the word. Do you know why this is?
I am asking this for a friend, so no the code and naming of variables is not how I would have done it. Please don't correct me on these issues, I am working on helping him fix how he names variables and what not.

Re: problem with indexOf() and contains()

Have you tried debugging? Maybe the variable isn't equal to the right thing (or anything) at the time you're trying to check it. If there is a problem between entering a word in a JTextBox and then storing that information in a variable then there are a few common logic errors that may be interfering:

1.) You may be using the wrong function for the JTextBox object.

2.) You may have a scope issue. If there is another variable that has the same name at a different "scope" or visibility the variable might be mis-assigned.

3.) The variable is being overwritten or the code that assigns the variable is never being called.

I would check those three things out, and if you still can't figure it out debug! Most IDEs have a debugging feature, which takes you line by line and displays the information about all the variables in the program.

*It would also help if you put all the code in between the [ code=java ] and [ /code ] tags, so that it's easier to read.

What the user enters in the JTextField is stored to the variable fine, I out put that variable just a couple of lines later. But when I test it in the indexOf() or contains() methods, it does not work.

What do you think indexOf does? I can't really clear up the problem without knowing what you expect it to do and what it is doing.

I expect it to return where in the word the letter is.

It always returns a -1, correct? If the number it's returning is not a -1 then it's getting a value.

  482.       ImageIcon waterfall;
  483.       JButton hangmanButton;

  485.       String array[];
  486.       AudioClip click;
  487.       Font font1;

on which line do you get this error? I'm trying to find which function gos to the "input letter" button, but there are so many functions named GameButton#Action that it's hard to figure it out.

I would just point out that you are checking the entry against the string in array[1] every single time, but showing a value based on your generator array[generator1-1] in the JOptionPane
Java Syntax (Toggle Plain Text) 
  1. a = array[1].indexOf(guess);
  2. JOptionPane.showMessageDialog(null, "" + guess + " " + array[generator1-1] + "  "+ a);

I figured out your problem. The variable "guess" is where the user input is stored. If the user typed in a d guess looks like this:

" d".

It will never find that in the code because there aren't that many spaces in a row in any of your words! Use the .trim() function on line 262 where you have the following code:

a = array[1].indexOf(guess);


The toLowerCase part so that it always compares to a lowercase value so that capitalization doesn't matter.

Also, the word will always be the second entry, or dictator. To fix this, enter generator1-1 where it says 1 in array[1].

Your code should look like this:

int a = 0;
guess = guessField.getText().trim();
String userGuess = "i";
String word = array[generator1 -1].toLowerCase();
a = word.indexOf(guess.trim());

JOptionPane.showMessageDialog(null, "" + guess + " " + array[generator1-1] + " "+ a);

the trim() to get rid of all the spacing, replacing the 1 with generator1-1 and adding the .tolowercase().

Dear,

Decide first, whether you want to search a string from an array of string or a string from another string.
