Java Problem Overview

In a Java .properties file we can do single line comments with #.

Is there any way by which we can do multi-line comments?

Java Solutions

Solution 1 - Java

Unfortunately not! Java properties file only have single line # comments.

Solution 2 - Java

If you use Eclipse, you can select multiple lines and comment all with a shortcut (Ctrl+/ by default). Same shortcut uncomments the lines, but you have to pay attention no to select any empty line, which will cause the non-empty ones to get commented more than once.

These apply to Eclipse, but I guess many IDE:s and some editors offer similar functionality.

Solution 3 - Java

.properties files do not have multiline comments.

Since JDK 1.5 Properties have XML support, and XML format supports multiline comments. See javadocs.

Solution 4 - Java

I have made a class that handles comments in properties. Both general header comments and comments for individual properties.

Have a look at : CommentedProperties JavaDoc

The jar file can be downloaded here : Download jar file from sourceforge

Solution 5 - Java

We can use Ctrl+/ to comment multiple lines in properties file. But it will put # for blank line also.

Solution 6 - Java

Select the content to comment out and press ctrl+/ on the eclipse editor

Solution 7 - Java

Java properties file only have single line (#) comments. If you have to comments in the multiple lines then you have to use # symbol at the beginning line of the code.

Solution 8 - Java

If you are using Eclipse there is this shortcut Ctrl+Shift+A that turns on selecting a column, so you can just drag through all the rows you need to comment and add # (this will add it to all rows). It will be the same when you want to delete the #. To turn off the column selecting mode you have to again press Ctrl+Shift+A.

Solution 9 - Java

We can use Ctrl+/ to comment multiple lines in properties file.

Solution 10 - Java

As I know, in file application.properties can only use tag '#' to comment.

Solution 11 - Java

Yes you can comment multiline in java properties file by using shortcut key Ctrl+/.

Solution 12 - Java
