1,947 PointsAm literally banging my head on wall... What is wrong with the statement in { }
I don't understand why line is also set to 0, and why there is a return value and where does that go. Also, what is wrong with the conditions in { }
Help please..
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 */
if(lastName.charAt(0) >= 'A' && lastName.charAt(0) <= 'Z') {
line = 1;
}
else {
line = 2;
}
int line = 0;
return line;
}
}

int line = 0;
This line therefore needs to be above the if-statement. The if-statement is almost correct, but remember that it should only be from A-M, and not from A-Z that the condition should be true.
Putting these two things together gives the below code, which solves the exercise.
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;
if(lastName.charAt(0) >= 'A' && lastName.charAt(0) <= 'M') {
line = 1;
}
else {
line = 2;
}
return line;
}
}
