Hi
There is a String class and some methods are associated with it. Read this class and their methods , your problem will be solved

The String class should solve the problem, providing you don't need anything exotic (like "delete all words that start with an 'h'"). But even then, you'll be able to use the given methods to solve the problem, it will be a bit more work though.

Arg, didn't think of that. But at least I wasn't totally mistaken:
The package java.util.regex is only provided from java 1.4, some of it even from java 1.5 onwards, so for backwards compatibility... ^^ OK, hardly anyone uses something older than 1.5 these days, but you never know! :-D

Spoiler: removing part of a String is identical to replacing that part of the String
by nothing, i.e. the empty String "". There's no need for all those statements
(what is "removedpart"?)

kind regards,

Great work. You'll often find that those doc pages usually have what you need.
