I am alittle confused!

Question

I was wondering do you think i could be having a probelm with import java.util.Scanner because of my version?
I am also having a problem with compiling with the import javax.JOptionPane
my issue is tha i have coppied two programs for betum out of a book, and one i worked on with my teacher in my Intro to Algorithm class and I was having problems when i compiled.
here is a sample of the code compiled
import javax.swing.JOptionPane;
public class ComputeLoan
public static void main(String[] args)
String annualInterestRateSring = JOptionPane.showInputDialog(
"Enter yearly interest rate, for example 8.25");
double monthlyInterestRate =
Double.parseDouble(annualInterestRateString);
double monthlyInterestRate = annualInterestRate / 1200;
String numberOfYearsString = JOptionPane.showInputDialog(
"Enter number of years as an integer, \nforexample 5:");
int numberOfYears = Integer.parseInt(numberOfYearsString);
String loanString = JOptionPane.showInputDialog(
"Enter loan amount, for example 120000.95");
double loanAmount = Double.parseDouble(loanString);
double monthlyPayment = loanAmount * monthlyInterestRate/ (1
- 1 /Math.pow(1 + monthlyInterestRate, numberOfYears * 12));
double totalPayment = monthlyPayment * numberOfYears * 12;
monthlyPayment = (int)(monthlyPayment * 100)/ 100.0;
totalPayment = (int)(totalPayment * 100)/ 100.0;
String output = "The monthly payment is" + monthlyPayment +
"\nThe total payment is" + totalPayment;
Joptionpane.showMessageDialog(null, output);
he told me to check what version of Java i had so i did and i discovered that i was using vs 1.4_2-12. What i am confused about, if this is the problem, is that off dowload page i downloaded the JDK 5.0 and installed it, so why is it version 1.4 and not version 1.5?
Any answer would be greatly appriciated.

Because in your path you're telling your computer to look for java 1.4 before it looks for java 1.5 Edit your path and it'll work.
