问题
In Java the following is completely valid:
if (x == null)
Y();
else
Z();
I personally don't like it at all. I like all my IF statements to have braces:
if (x == null) {
Y();
} else {
Z();
}
The eclipse formatter is wonderful and can beautify my code in many other ways.
Is there a way to have it add the braces to IF statements?
回答1:
Under "Preferences": Java > Editor > Save Actions
1) Check "Additional actions"
2) Click "Configure…"
3) Go to the "Code Style" tab
4) Check "Use blocks in if/while/for/do statements" and configure to your preferences
回答2:
Yes.
Eclipse menu: Source -> Clean Up...
Configure... -> Code Style -> Use blocks in if/while/for/do statements.

In Eclipse Oxygen (2017+), that option is now at:
Window
-> Preferences
-> Java
-> Code Style
-> Clean Up
-> Edit
-> second tab "Code Style"
After changing, select the corresponding parts of your code and run the "Clean Up" option.

This is what I did: Eclipse -Preferences-Java-Code Style-Formatter-Edit-Braces Select next line as desired in each box then save as a different name (your choice).

I usually do it by creating a code formatter by copying the built in eclipse formatter, here:
Windows > Preferences > Java > Code Style > Formatter
Select the profile that you have just created. and click on Edit and go to "Braces" tab.
Change the braces placement as you like (it's a WYSIWYG kind of editor, makes it easy) .
When I need to format, I just select all the text and Ctrl+Shift+F and it works fine for me.
