1,188 PointsHelp with getForLine method
I cant get the first letter of the last name to compare if it starts with A-M
public class ConferenceRegistrationAssistant {
private String mLastName;
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 */
char name = lastName.indexOf(0);
if (name=='A'||name=='B'||name=='C') {
line = 1;
return line;
} else {
line = 2;
return line;
}
}
}

2 things!
Since we want a char value, we have to use the charAt() method rather than the indexOf() method
now that we have the char, we can use it to compare its value to 'M'. Yes you could chain together a lot of or statements but, going with the mantra of not repeating ourselves, using if(firstLetter < 'M'){...} works too!
Hope this helps!
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 = 1;
char firstLetter = lastName.charAt(0);
if(firstLetter < 'M'){
line = 1;
} else {
line = 2;
}
return line;
}
}
