First Swing Applet

[p3aul]

hi!I am using Jbuilder2006. I have a simple Swing applet with a button and a label. I double-clicked on the button and added this code:
jLabel3.text = "Hello";

I have attempted to do this like a Delphi statement. I'm probley wrong!

this is the error I got: "myswing.java": text has private access in javax.swing.JLabel at line 91, column 9

My jLabel3 is declared as public by default(written by JBuilder) How do I make it private? or is there another way?
Thanks in Advance!

Try

jLabel3.setText("Hello");

Incidentally, you're going to get nowhere fast if you try using other languages as a basis for attemting valid Java syntax. You need to do some reading to get a grounding about how to structure classes and how to invoke methods on objects etc. One book I found useful is the 'Thinking In Java' by Bruce Eckel. You'll find it on the web with Google.

Thank you Tim!
Since I am so new at this I was trying to do something simple in terms that I already knew. Thats why I chose JBuilder. I firgured the folks at Borland would put out a Java product that would work similarly to Delphi or C++Builder. The Java language is so hard to learn with their mouselisteners and other odd programming constructs! It would have been just as easy to use Pascal or C++ syntax?

Well, Java is an Object-Oriented language and the syntax is designed around this concept (so Pascal syntax, being non-OO, would obviously not do).

Java isn't just a matter of syntax, as you have noticed. We have constructs which may appear odd at first. They make more sense as you go along. The OO idea of code re-use extends to concept re-use too. Once you've 'got' how a MouseListener works, you're very likely to understand every other kind of Listener too.

The JBuilder IDE itself may look familiar to users of other Borland IDEs. I don't know. It does, however, handle Java like Java. There is no other way. Sun have specified the Java standard, not Borland.

Tim, Pascal is OO also. By Pascal I meant Object Pascal, but what I use is Delphi, based on the Pascal language. I noticed, after I double-clicked on the button, I didn't get a button-click event like in Delphi, but a actionPerformed event and instead of settting a property "text", I used a function, setText() to set the property. See, I am learning. By using Jbuilder, I didn't have to do all that coding as I would have to have done had I written the code in Notepad or some other text editor.
Again, thanks for your help!
