how to update Jtable by editing its cell with netbean.
someone help please

I think you'll have to explain this in detail. Here, Netbeans is the IDE where I edit code. https://en.wikipedia.org/wiki/NetBeans

So your topic is about updating which coupled with your question my answer would be "open your project in Netbeans, edit the thing you want to update and save your files and project."

Maybe you meant something else entirely.
