regex for character code 0 in java

Question

How does one write a regular expression in java that will match all strings without the character code zero?

I've tried:

Pattern.compile ("[^\0]");

and

Pattern.compile ("[^\u0000]");

Thanks.

Answer 1

Your first regex is almost right, but it only matches a single character that is not \\0 . Try changing it to:

Pattern.compile ("[^\0]+");

This should match one-or-more ( + ) characters that are not \\0 .
