I really like Kate as an advanced editor with syntax highlighting, auto-completion, plugin support. I would then use the Terminal pane at the bottom to run my code during development.

However, if you want a full IDE with included dependency management, test runner, and debugger it’s probably not enough.

One of my professors said you don’t need an IDE, the Linux system already is a development environment. Not sure that I fully agree with that, especially thinking of things like Android Studio that include the virtual machine smartphone, but it’s still an approach thing that is worth trying out.
