Your question is not clear on what you want to do with the extra text field, but you are already manipulating two fields just fine. Why can you not just add the third and do whatever you want with it? What is giving you difficulties?

If you passed the animation reference to the Timer as a final reference (which would have been required for an anonymous inner class for the ActionListener), then you can't re-instantiate that reference and have it still work in the Timer. Have you tried recreating the Timer?

You could use a while loop, but with arrays a standard for() loop or a foreach loop is usually preferred. A do while loop is seldom used to loop an array because a do while always executes at least once before the test and you would have to make sure …

See the api for [URL="http://java.sun.com/javase/6/docs/api/java/text/DecimalFormat.html"]DecimalFormat[/URL]. Also, after 50 posts, you should be familiar with [noparse][code] [/code][/noparse] tags - use them.

That depends entirely on the constructors you have written for DisplayDie and DisplayPanel.

Having the sleep() in main() after you have called the mortArray() method will not cause your output to pause. The loop will continue to run until complete and then return to execute the rest of your code in main() - which is your pause code. You need to place the …

It doesn't need to be reloaded - it just needs to be reset. How to do that depends upon how you have structured the code that initializes it.

The demo class needs to create "Ages" objects and use the methods you have defined. As written your demo just defines some variables and prints the "avgAge" - which is still 0 because you haven't done anything with it.

This is your third thread on the [U]exact[/U] same issue and this has been answered in the other two already.

Another loop inside that one on [code]while( tokens.hasMoreTokens() )[/code] is all you need.

The error message should also include the name of the class that is not found. Check that method for classes you may have missed on the class path and if it is a third-party library check that those runtime dependencies are also in your classpath.

The stack trace clearly indicates that in your actionPerformed method on line 99 that you are attempting to call a method on an object that is null. Examine the call that is being made on line 99 and examine why it might be null.

Your question is too vague. By "upload" do you mean with a JSP page or from a desktop Java application? (This is the Java forum by the way. There is a separate JSP forum here:[url]http://www.daniweb.com/forums/forum24.html[/url]) Without more information no one can really help you.

You haven't ended the main() method block. Until you do that you can't start a new method.

The row must be added to the TableModel, not the JTable as you are attempting. In particular, that method is provided by DefaultTableModel and is not in the general TableModel interface, so you will either need to keep a reference to the DefaultTableModel that you are creating[code=java]DefaultTableModel tableModel = new …

There is no guaranteed return path because your return is within a conditional statement. This means that when your if() test is false the function has no return value - and the compiler won't allow that. You need a return outside of the if statement as well.

[icode]DecimalFormat("#.##")[/icode] will show up to 2 decimal places if applicable.

Then you need to make sure that the BufferedWriter is being created correctly and the "myList" has been initialized by the point you are calling that loop.

Because your toString() method is not returning a string, it's just printing stuff out to the console. It needs to build a string and return it. Also, after 18 posts, you should learn to use [noparse][code] [/code][/noparse] tags around code that you post.

Take a look at this example on disallowing edits: [url]http://exampledepot.com/egs/javax.swing.table/NoEdit.html[/url] The signature of the method that they are overriding should give you a pretty good idea on how to disallow editing on any particular row or column.

The stack trace is showing the error occurring in sigmoidActivationFunction [code]at newtonsMethod1.sigmoidActivationFunction(newtonsMethod1.java:118)[/code] and if you look at the constructor you are using for BigDecimal there the error should be pretty clear.

You actually need to add the data to the TableModel.
