Help me java says cannot invoke javax.swing.JFrame.add(java.awt.Component) because this.frame is null
Hi,
I have IntelliJ and am trying to make a GUI application and it says this:
cannot invoke javax.swing.JFrame.add(java.awt.Component) because this.frame is null
Someone told me the JFrame thing is null, but didn't tell me how to fix.
Please help me fix the issue.
Thanks,
pikachuwu
Re: Help me java says cannot invoke javax.swing.JFrame.add(java.awt.Component) because this.frame is null
Please post the code that has the error(wrapped in code tags). Post complete code that can be compiled to see the error.
If a variable has a null value, the program needs to assign it a valid value.
For example:
JFrame myFrame; // myFrame has a null value myFrame = new JFrame(); // assign value to myFrame
If you don't understand my answer, don't ignore it, ask a question.
