I have a text like: 

DISK_ERROR_MESSAGE = "Server %s is using more than 90% of the disk."

The problem, is when I try to do something like:

String.format(DISK_ERROR_MESSAGE,host.getName())

Java launches the error:

Method threw 'java.util.MissingFormatArgumentException' exception.
java.util.MissingFormatArgumentException: Format specifier '% o'

The problem is that % of the 90%.

But I don't know how to avoid it without separating the text in two strings.

To escape %, you will need to double it up: %%.

So, you need to change your string to 

DISK_ERROR_MESSAGE = "Server %s is using more than 90%% of the disk."
