Why doesn't my code work? I think it's some weird thing about java but still I am not understanding why.

String lastNameLetter = lastName.substring(0, 1); if (lastNameLetter < "M") { lineNumber = 1; } else { lineNumber = 2; }

Close, but there's two issues:

  • you can't compare strings that way, but you can compare charcters
  • the value should be 1 if the character is "between A and M" inclusive 
if (lastName.charAt(0) <= 'M')
