Also you won't be using all those languages you mentioned. I have learned all those too but once you become a developer you end up specializing in one of those. Java has its own path and same for C++. I was PHP developer so I didn't do those above languages after the degree. Also Java script and HTML usually done by front end developers.

I agree with @rudra about for learning scripts, the best tool is notepad. But once you are working on Project having an IDE is a must.
