Java正则表达式问题

Question

Suppose I have a string "July is busy". And I need the string without "July". How can I do it with using regex ?

Thanks.

Answer 1

So you want to remove the first word from a string?

Try

String resultString = subjectString.replaceAll("^\\s*\\w+\\s*", "");

Answer 2

You can do something like this:

import java.util.regex.*;
Matcher m = Pattern.compile("^July(.*)\$").matcher("July is busy");

// if you had a match, the extra would be here:
if (m.matches()) {

    // match count:
    m.groupCount();

    // ' is busy'
    String rightOfJuly = m.group(1);
}
