Simple way to reorder methods of a Java class in IntelliJ?

Question

Is there a simpler way of reordering methods within a class source file in IntelliJ than cutting and pasting the code manually? Nowadays I often need this while refactoring legacy code, eg to move related methods close to each other in the source code.

In Eclipse AFAIK there is a view similar to the Structure view of IntelliJ, where I can drag and drop methods around. However, this does not work in IntelliJ and I couldn't find any hints from its help either.

I am using IntelliJ 9.0.2 to be specific.

Answer 1

You can select a method name and hit: Ctrl + Shift + Up or Ctrl + Shift + Down to move it up and down.

On OS X: Cmd + Shift + Up or Cmd + Shift + Down

Beyond this the Rearranger Plugin lets you move methods around quickly, and even define a standard ordering based on your coding convention.

Answer 2

Not a perfect answer yet , due to a bug in IntelliJ.

Though IntelliJ offers this feature implicitly, but it needs to be enabled as well as fixed. The OP's suggested way is technically arranging methods in depth-first order. However, if you use Breadth-first ordering(which works properly), it should reduce the manual work of moving functions by a lot, by arranging all caller and callee methods together.

The appropriate action for this is Rearrange Code. This has no key assigned to it, but you can define your own using Preferences->Keymap.

IntelliJ has a built in system that allows you to specify how to order your methods. You need to go to Settings (Ctrl + Alt +S) -> Editor -> Code Style -> Java -> Arrangement (tab) and scroll down until you find the icons with methods . There you can manipulate the options to sort them by visibility, or alphabetically, or to keep related ones grouped together. Here is a screenshot of my settings which will order methods automatically by visibility (public, protected, private) and alphabetically (az). The blue highlights show the currently selected rules.

With your cursor on the method definition line (you do not have to and press ctrl + shift + up or ctrl + shift + down , to move up or down respectively.

You can also to ctrl + shift + numberpad - to quickly collapse everything so you can focus on moving around (plain - works on my laptop as well, not sure why) and ctrl + shift + numberpad + to get back to see everything (ctrl-shift-equals works on my laptop as well).

Answer 5

选择一个文本块（按Ctrl-W几次），然后使用Ctrl-Shift-Up和Ctrl-Shift-Down移动它。

Answer 6

There is an automated way, which you can later tweak

Code -> show reformat file dialog

and tick "rearrange code" box
