I'm trying to create an array of Labels
I declare the array using:
Label example[];
at the top of me class, and in the constuctor tries to initialize it with:
Label[] example = { "ex1", "ex2", "ex3", "ex4", "ex5", "ex6 };
When I try to compile it, I get errors:
Incompatible type for array. Can't convert java.lang.String to java.awt.Label
Is there any way to initialize the whole array at once, or do I need to do something like:
example[0] = new Label("ex1");
example[1] = new Label("ex2");
etc...

Try this...
String example[];
In your constructor...
example = { "ex1", "ex2", "ex3", "ex4", "ex5", "ex6 };

String example[];
In your constructor...
example = { "ex1", "ex2", "ex3", "ex4", "ex5", "ex6 };

While that would probably work, I'm trying to create an array of Labels that I want to user further in my program, not Strings. I can probably just initialize them seperatly, but as I have a LOT of arrays that I am going to end up needing, I wanted to know if there was a quicker, more efficient way of doing this.

As far as I can see what you have been trying to do is assign an array containing Strings to an array containing Labels. But this is not possible. You will have to first create Label objects with the Strings and then initialise the array. Or create the array of Label objects with empty constructors and then set the text of each label. If someone else can suggest a better solution please do so.

Matthew,
The easiest way to probably do this is to have an array of Labels and an array of Strings:
<code>
Label example[];
String words[] = { "ex1", "ex2", "ex3", "ex4", "ex5", "ex6" };
example = new Label[words.length];
for ( int i = 0; i < words.length; i++ )
{
example[i] = new Label( words[i] );
}
</code>
HTH,
