Removing whitespace from strings in Java

Question

I have a string like this:

mysz = \"name=john age=13 year=2001\";

I want to remove the whitespaces in the string. I tried trim()

Answer 1

The easiest way to do this is by using the org.apache.commons.lang3.StringUtils class of commons-lang3 library such as "commons-lang3-3.1.jar" for example.

Use the static method "StringUtils.deleteWhitespace(String str)" on your input string & it will return you a string after removing all the white spaces from it. I tried your example string "name=john age=13 year=2001" & it returned me exactly the string that you wanted - "name=johnage=13year=2001". Hope this helps.
