Question

I have a string that contains 2 integer numbers separated by whitespace followed by any character string which includes whitespace.

Example:

23 14 this is a random string

How do I extract this is a random string?

The integers aren’t guaranteed to be double digits therefore I can’t figure out how to use indexOf and substring to extract this data.

Thanks in advance.

Wow. I can’t believe how much code some people write to do the simplest of things…

Here’s an elegant, one-line solution:

String remains = input.replaceAll("^(\\d+\\s*){2}","");

Here’s a test:

public static void main( String[] args ) {
    // rest of String contains more numbers as an edge case
    String input = "23 14 this is a random 45 67 string";
    String remains = input.replaceAll("^(\\d+\\s*){2}","");
    System.out.println( remains );
}

Output:

this is a random 45 67 string
