How to set value for jlabel java

Question

I know that to set value for the label you must write:
Labelname.setValue("string");
But it never work on Jframe on Eclipse.

Answer 1

If you want to define text on your jlabel then use :

labelName1.setText("something");
//labelName must be same as you set the value of your label name //

And you don't want to set text of jlabel then I don't know what value you want to change.!! Please be more clear. :)
