在IntelliJ中重新排序Java类方法的简单方法？

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.

Answer 4

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
