Searching inside a String

Question

Hi,
Can anyone tell me what's the best way to search something inside a String?
My problem exactly:
I have to read a sent message and seach for the "To:" substring, in order to identify the user id that follows. I think this can be achieved with a Matcher, but I don't understand how it works. Van anyone give me an example?
Thanks

String string = "Madam, I am Adam";
    // Starts with
    boolean  b = string.startsWith("Mad");  // true
    // Ends with
    b = string.endsWith("dam");             // true
    // Anywhere
    b = string.indexOf("I am") > 0;         // true
    // To ignore case, regular expressions must be used
    // Starts with
    b = string.matches("(?i)mad.*");
    // Ends with
    b = string.matches("(?i).*adam");
    // Anywhere
    b = string.matches("(?i).*i am.*");
