regex - Java Regular expression special charecters -

i want replace xx* x.

i tried string.replaceall("xx*", "x");

but in regex * special need give \* give \ in java need give \\

==> should work string.replaceall("xx\\*", "x");

but when string contains xx* above statement fails in replacing xx* x

please thank you

1. you have reassign result of replaceall() call string variable - method returns new string opposed modifying string call on.

2. don't use replaceall()!! use replace() when dealing literal strings:

   string = string.replace("xx*", "x");
