Def agree that Java is less readable, and there will always be shorter ways of expressing things (such as a for-loop). But I do think an IDE does, and could do a lot more to help: hide the generated boiler-plate code from me, show me a visual map of the source structure so I can jump to places quickly, and perhaps even summarize certain code blocks for readability (eg why not summarize a standard MAP for-loop, so that it becomes editable if I click on the summary?)

There are many other things that an IDE could do beyond validating my code, function arguments, giving me hints, auto-completing variable names, code-blocks, etc. All those things make Java & C# much more productive than people think. The worst bit is actually dealing with libraries, whereas with Python/PHP much more stuff is built-in.
