How do i open JFrame in the same active window
Hello, I'm new to java and I'm having a project for school. Required to do design a waste collecting system which take in weight and print invoice to text file.
So my 1st question is:
How do I open JFrame, one after another, in the same active window ?
this is the startup page
then, when click on New Collection, it will appear this frame
in the same window.
This must be applied for the rest.
How can I display the data from button onto textfield ?
From the data in textfield, how can I export to a text document ?
Thanks for all the helps in advanced
