Decompiler for java

Hi all,

Is there any decompiler for netbeans to see source code from class file.

Hello,

for standalone java decompiler :

simple  : http://java-decompiler.github.io
complex : https://bytecodeviewer.com

for (simple) I keep some older version at hand, 'cause for very old 
class files they give better results
Sometimes.

Cheers,

     Davide

Why is having a built-in decompiler that big of a deal, if I may ask?

It seems odd to mix the Java and Javscript items. I have no need for the 
Javascript items, another programmer may have no need for the Java 
items, yet another may no need for either and have an entirely different 
list.

I have a need for a java decompiler about once every 5 years, if that, 
for about 10 minutes.

This may be lack of imagination on my part, but the only code completion 
feature I miss, would the equivalent of "Assign Return Value to New 
Variable" for java for-each statements.

Yaah! It would be a good advice. Though it's challenging for me, but I will
try it.
Thank you.

Let's just put this under "better code completion". You don't know that
only ML can provide this and it being ML will not necessarily make it
better. For JS we could provide better code completion in commercial
tooling using better static analysis compared to what NetBeans does by
default. Plenty of things to improve using classical engineering before we
need to bring in AI.

I think SQL support exists?

Sure, problem is few libraries in this area, especially under good license
terms. I think a good one was GPL last I checked which the ASF will dislike.

That's on toolkit. Other real life developers never used it.

"Machine learning capabilities to code completion" - don't let yourself
misled by the other IDE's marketing machines :)
I'd say code completion is better in NB than Eclipse.
Code refactoring & other capabilities are better than in VS.
I for one would replace that list of yours with "better jpms support"
although the last time I tried it was in NB 9 I think, so it may have
improved in the meantime. Can't remember exactly what the issue was but
switching to Eclipse unstuck that project.
And I'd throw in something like Eclipse Che on such a wishlist.

Still, Apache Netbeans requires some things to be usable as a true full
stack IDE for java and JavaScript at least. They are:

1. Machine learning capabilities to code completion.
2. Autocompletion support for database or SQL language and NoSQL support
like MongoDB.
3. A Decompiler for java.
4. React Native support.

at least these should be added into Apache Netbeans future releases to
gather more real life developers.
Hope for the best.
