Swing question

[BenH]

Hi there.

I am currently learning swing. My next program that I am supposed to design is to use a GUI. I know how to do that. How do I display text that includes variables? I tried JLabel, but I get an error which basically states I cannot use a variable with JLabel. It has to be a string. Is there any other way of doing this? Thanks!

I don't understand your question. You can do:

String variable = "some text";
label.setText(variable);

If you need more help then post your Short, Self Contained, Correct Example that demonstrates the problem.

Objects have a toString() method. Primitive types (int, etc.) can be converted using the static toString() method of their wrapper class. For example:

int myInt = 42;
JLabel label = new JLabel(Integer.toString(myInt));

There's also a lazy and inefficient way of doing it:

int myInt = 42;
JLabel label = new JLabel("" + myInt);
