Can somebody please give me some guidance on the line numbers objective? I'm completely stumped.

Everything I've tried gives me a long list of errors. I just need to be pointed in the right direction.

You are making it more complex than need be. You can eliminate the additional variables and use lastName.charAt(0) in your comparison in the if statement .

if (lastName.charAt(0) < 'N') {
    lineNumber = 1;
}
else {
    lineNumber = 2;
}

That makes perfect sense. Thanks a lot!

Some hints:

  • You will want to use an if else statement in assigning lineNumber a value of 1 or 2
  • You can use the charAt(0) method to get the first character of lastName
  • You can use character < 'N' to check if a character is between A and M.

This is the code I have generated so far:

int first = 1;
int second = 2;
String line1 < 'N';
char letter = lastName.charAt(0);
boolean manage = line1.indexOf(letter) != -1;
if (manage) {
  lineNumber = first;
} else {
  lineNumber = second;
} 
return lineNumber

}
