Java Java Objects (Retired) Creating the MVP Comparing Characters

HOW DO YOU COMPARE CHARACTERS I

HOW DO YOU GO ABOUT COMPARING CHARACTER

ConferenceRegistrationAssistant.java
public class ConferenceRegistrationAssistant {

  public int getLineFor(String lastName) {
    /* If the last name is between A thru M send them to line 1
       Otherwise send them to line 2 */
    int line = 0;
    return line;
  }

}

Hi Ashford,

String objects have a lot of methods that can be called, one of which is charAt, which accepts a number as the index value into the string.

String fruit = "Apple";

fruit.charAt(0); // 'A'

Reference: Oracle Java Docs - String

Also, Craig provides a really good tip that characters can be compared using > and <.

if ('a' < 'b') {
  System.out.println("Yep, 'a' comes before 'b'");
}
