This is a big problem. I want to list a common tool that can be used by a Java programmer.

It is required to perform a static code check before release.
(2)
Clover, focus on your unit test coverage rate

(3)
Checkstyle
Code style check

3. build and deploy tools:
Ant
Or Maven
Now Maven is the mainstream. Use nexus to build a Maven private server.

Jenkins
. No worries about code quality.

4. Version Management tools:

Or dump memory is used for analysis:

Jmap-dump: file = test. Bin PID

3. To analyze the dump heap file, you can use jhat:

Jhat test. Bin

After the analysis is complete, you can view the heap status in the browser. The analysis results of this tool are still original. You can also use
Eclipse mat
Plug-ins for graphical analysis, or IBM
