Another Java debugging tool to use in 2021 for developers is Eclipse. Eclipse is an open-source IDE with a built-in Java Debugger. Like Rookout, Eclipse is also a cross-platform IDE for developing modern applications.

Eclipse comes with a lot of features such as setting breakpoints, perform step execution, inspect variables and values, suspend and resume threads, that help developers declutter programming. Eclipse supports PHP, C, C++, and other languages.
