Is there a good exception class in JDK for the case where user input is too long?

Question

I'd like to process user input and throw an Exception if it exceeds some fixed limit of character. Example:

public String read(Reader r){
    String input;
    //get the input
    if(input.lenght() > 100)
         //throw what?
    return input;
}

Should I craft my own exception class for that case? I presume that just using IllegalArgumentException would not be fine.

Answer 1

You will have to make your own Exception

Refer: How to create custom exceptions in Java?

Try this:

public String read(Reader r){
    String input;
    //get the input
    if(input.lenght() > 100)
         throw new Exception("Write your own stuff");
    return input;
}
