Remove first white space in Java

Question

How would I remove the first white-space in Java?

Right now I am using this:

if (str.charAt(0) == ' ') str = str.replace(" ", "");

Answer 1

Just use str.trim() to get rid of all leading and trailing spaces.

Answer 2

Use replaceFirst() instead of replace().

TO get rid of all leading spaces you can use

str = str.replaceFirst("^ *", "");

The ^ is just to make sure that the spaces are actually at the start of the string, which it seems like you wanted. If that is not the case, just remove it.
