Java – is there a tool in eclipse, an eclipse plug-in, or an external program that can automatically restrict access to modifiers?

I used to be very bad at restricting access to my variables / methods / classes. When I shouldn't, I tend to use public places

I just want to know if there are any tools - plug-ins, external or others - that can search your source code and find what calls your variables / methods / classes. If it is too high, it will change the visibility

So, for example, if I have a public variable and nothing outside the class calls it, the tool will reduce its access to private variables

For some old projects with many public variables, I mainly need this It takes me a long time to filter out all these contents. When I go back to these projects and deal with them again, it is very annoying / inefficient to make them public

Solution

Look at the ucdetector: unnecessary code detector Eclipse Plug-in It will create a tag for the following issues (which appear in the eclipse issues view):

>Unnecessary (dead) code > visibility can be changed to protected, and the default or private > field method can be final

It also supports eclipse quickfixes to automatically adjust member visibility
