Attach the Java Source Code

Question

I cannot for the life of me attach the java source code to eclipse so I can see the inner workings of the language. Not even something as simple as the String Class.

Answer 1

Easy way that just worked for me:

1. Check if you have a jdk installed (it is usually in "Program Files\Java", if you don't have one, install it.
2. Link it to eclipse. In Preferences --> Java --> Installed JREs remove the JRE installed and add the JDK.

Then the project will detect it and add the new libraries from the JDK. At the end of this process it looks like the screenshot I attach.
