    Default SetVisible causing problem

    Below I have pasted some code and the error messages it raises. It is supposed to produce a window saying Saluton Mondo. It doesn't do this! The code is copied from a tutor book and as far as I can see it is accurate so why is setVisible throwing an error? is it the code or is it some feature of the NetBeans IDE? it also seems to have a mild issue with catch(Exception exc); if i click in the text it says variable exc is not used.

    import javax.swing.*;

    public class SalutonFrame extends JFrame {
    public SalutonFrame() {
    super("Saluton Mondo");
    setLookAndFeel();
    setSize(350, 100);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    SetVisible(true);
    }

    private void setLookAndFeel(){
    try {
    UIManager.setLookAndFeel("com.sun.java.swing.plaf. nimbus.NimbusLookAndFeel");
    } catch (Exception exc) {
    }
    }

    public static void main(String[] args) {
    SalutonFrame sal = new SalutonFrame();
    }
    }


    run:
    Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: SetVisible
    at SalutonFrame.<init>(SalutonFrame.java:9)
    at SalutonFrame.main(SalutonFrame.java:20)
    Java Result: 1
    BUILD SUCCESSFUL (total time: 8 seconds)

    Default Re: SetVisible causing problem

    .....
    setVisible
    SetVisible

    Do you see the difference?

    Default Re: SetVisible causing problem

    Hi;
    Thanks, yes I do! Just came back having had another look at the original after another file ran no problems. Was going to delete the post and slink away in embarassment! Still thanks for responding.
    Regards EB
