How to use Hotswap in Netbeans?

Question

How to do that? I can't find any option for it in the IDE... Please help me, I'm clueless.

Answer 1

• Run your app in "debug" mode
• Modify your .java files and save them
• Click on the "Apply Code Changes" button that appears on the toolbar (it looks like three linked green rectangles, or Tools -> Options -> Java -> Java Debugger -> General -> Appl code changes after save)
