I am trying to build multiple JFrames and give them a layout of FlowLayout but I am not able to get the FlowLayout to work. The JFrames are working fine but not the flowlayout. The JTextField also works but not the JLabel.

here is the code I have:



I am not getting any compilation errors so all objects and variables are initialized and found. I am not getting any nullPointerException either.

I appreciate the help

Read the Swing tutorial on "How to Use Flow Layout" for a working example.

The FlowLayout is the easiest layout manager to use. We are not going to debug your program for you. Start by adding one component to the panel and add the panel to the frame. Once that works you add the second component. Once that works add the third.

Don't write your entire program up front. Do it one step at a time and make it more complex as each step works.

This is basic debugging.

To increase your chances of getting help you should create a SSCCE (Short, Self Contained, Compilable and Executable, Example Program), that demonstrates the incorrect behaviour. (What you posted is NOT a SSCCE).

What Rob said.

In your oneJFrame() you got two mistakes.
1) You are calling the set visible and then adding the child components
2) You are not setting the layout to frame1

Thanks for the help, I already had one JFrame working just fine, but couldnt understand why the others wouldnt work. So thanks again for pointing out my problems.
