Question

I want a regular expression which can remove spaces before or after = in java.

For example consider a string

String str="Name   =  Aniket";

I want the result to contain a strring which contains no spaces before or after =. That is result should contain "Name=Aniket".
How to do it in java?

Answer 1

I want a regular expression which can remove spaces before or after = in java.

The following solution will remove all whitespace before and after a =, just as it should do in the example you provide.

str = str.replaceAll("\\s*=\\s*", "=");

will get rid of whitespace before and after every =, and leave the = where it was.
