Eclipse java editor: format code

Question

Eclipse Java EE IDE for Web Developers.

Version: Mars.2 Release (4.5.2)
Build id: 20160218-0600

Eclipse formatting code does not work for source code containing the following case:

String foo = (bar!=null)? value1 : 
        value2;
System.out.println("hello world");

the value1 and value2 can be very long, so split into two lines.

Java editor: format the code above (CTRL + I), and get the following result:

String foo = (bar!=null)? value1 : 
        value2;
        System.out.println("hello world");

Source code can be very big, and it is convenient to select all and then press (CTRL+I) to format the whole code. Is there a way to avoid the formatting error above? Thanks.

Hm, make value1 and value2 small by making them methods perhaps. — Hovercraft Full Of Eels

You can use single line comments // to force the eclipse code formatter (and other code formatters) to preserve the line(s) you want. Something like

String foo = (bar != null) ? //
        value1 : //
        value2;
System.out.println("hello world");

Yes, I've done a similar thing today with an enum that I've created, to try to prevent bad formatting.

@Dave I formatted the code in this post with eclipse Mars.2
