Bummer! i entered Anderson and expected to get back line 1 as A comes before M. im not able to understand what is wrong

public class ConferenceRegistrationAssistant {

String firstLine; 
String secondLine;

public int getLineFor(String lastName) {
int line = 0; 
if (lastName.matches("[A-M?]")){ 
firstLine += lastName; 
} else { 
secondLine += lastName; 
} 
return line; 
}

}

Alright, above I've put your formatted code since it'll be a LOT easier to read. To add formatted code in the future, add three fancy apostrophes (on the tilde key above the tab key on your keyboard) before and after your code.

It looks like you are trying to add the last name to the first line. However, you are just supposed to return an int that says which line the person is supposed to go to. After that, you need to compare the first letter of last name (hint charAt) to the character M. If it is less than or equal to M, you will return 1. Otherwise, you will return 2. So...

public int getLineFor(String lastName) {
    if (first letter of last name <= 'M') {
        return 1;
    } else {
        return 2;
    }
}

The code as written above will obviously not work, but it's a jumping off point for you. Fill in what you need.

It is Specified in you can use character Comparison Here I go public int getLineFor(String lastName) { int line = 0;
if (lastname.charAt(0) > 'M') { line++; } else { line = line + 2; } return line; }
