Switch statement & system.read.in

Question

I am attempting to code a java text program that will calculate and print out 3 different mortgage's, I am trying to use a switch statement to select which mortgages I will output. I am trying a simple switch statement first and I am stuck, Can anyone help.
//test switch case program
import java.text.*;
import java.io.IOException;
//import java.util.*;
//import java.lang.*;
public class TestIfElse
{ // start of main method
public static void main (String[] args)
          // throws java.io.IOExceptions
{//start Main
double interestRate = 0;
int year;
double loan;
char choice;
//enter # of years & find interest rate
System.out.println("Enter Years:     7, 15, 30 only:");
choice = (char) System.in.read(); //System.in.read();
switch (choice)
case '1' :     interestRate = 7.25 / 1200;
System.out.println(+interestRate);
break;
case '2' :      interestRate = 8.50 / 1200;
System.out.println(+interestRate);
                         break;
               case '3': interestRate = 9.0 / 1200;
System.out.println(+interestRate);
                         break;
default : System.out.println("oops");
}

Answer 1

ok i couldnt get the switch to work so I tried this and now it wont read in ?? I am about ready to give up. can anybody help??
