Problem

Your sixteen year old brother comes to you for help in a programming assignment he has in school. He claims doesn't even understand his own code. His program is supposed to determine what the interest rate would be in a $15,000 car loan, depending on how long the user wants to take to pay it off. Here are the conditions:
36 months: 7.5%
48 months: 8%
60 months: 9%

You glance over his work and notice how badly structured his program is. Edit the snippet of code below without the use of any editors and compilers, and explain why the edit was necessary.

int answer=0;

int months = Integer.parseInt(String answer = JOptionPane.showInputDialog("How long will it take you to pay off your loan? 36, 48, or 60 months?:"));
if(36 == months); answer = 7.5;
else if(48 == months) answer = 8;
else if(60 == months) answer = 9;
