Question

What method would you suggest to normalizing a text in Java, for example

String raw = "  This is\n  a test\n\r  ";
String txt = normalize(raw);
assert txt == "This is a test";

I’m thinking about StringUtils .replace() and .strip() methods, but maybe there is some easier way.

Answer 1

Try the following if it is just a matter of whitespaces

String txt = raw.replaceAll("\\s+", " ").trim();
