Newbie help with java :(

Question

Hey guys bare with me as this is my first assignment for my Java class. Here is the assignement and my class must be named payroll1. Any help on correcting or pointing out what is wrong with my code would be great.
Create a non-GUI based Java application that calculates weekly pay for an
employee. The application should display text that requests the user input the name of the employee, the hourly rate, and the number of hours worked for that week. The application should then print out the name of the employee and the weekly pay amount. In the printout, display the dollar symbol ($) to the left of the weekly pay amount and format the weekly pay amount to display currency.
// Payroll1.java
// Payroll1 that displays calculates weekly pay for an employee
import java.util.Scanner; // program uses class payroll1
import java.text.NumberFormat; // program uses class NumberFormat
public class Payroll1 {
// main method begins execution of Java application
public static void main(String[] args) {
// create payroll1 to obtain input from command window
payroll1 input = new payroll1( System.in );
NumberFormat currency = new DecimalFormat("\u00A4 #.00");
String fname; // first name to be entered
String lname; // last name to be entered
double hourly; // hourly rate to be entered
int hours; // number of hours worked to be entered
double product; // product of hourly and hours
System.out.print( " Enter the employee's first name: "); // prompt for name
fname = input.nextLine(); // read first name from user
System.out.print( " Enter the employee's last name: "); // prompt for name
lname = input.nextLine(); // read last name from user
System.out.print( " Enter the hourly rate."); // prompt for hourly rate
hourly = input.nextDouble(); //read hourly rate from user
System.out.print( " Enter the number of hours worked for the week."); // prompt for hours
hours = input.nextInt(); //read number of hours worked
product = hourly * hours; // multiply numbers
System.out.println("Employee Name is: " + fname + " " + lname);
System.out.println("Hourly wage is: " + hourly);
System.out.println("Weekly pay is: " + currency.format(product));
} // end method main
} // end class Payroll1
Here are the errors I receive when I run the program in RealJ
C:\IT215\payroll 1\payroll1.java:6: class Payroll1 is public, should be declared in a file named Payroll1.java

Please remove or make sure it appears in the correct subdirectory of the classpath.

Are you using J2SDK 1.5.0 beta 1 or J2SDK 1.4.2? Are you using the docs from 1.5 and the compiler from 1.4.2?
private java.util.ArrayList jobsList=new java.util.ArrayList(100); //-- 1.4.2 code
private java.util.List<Job> jobsList = new java.util.ArrayList<Job> (100); //-- 1.5.0 code (preferred style)
private java.util.ArrayList<Job> jobsList = new java.util.ArrayList<Job> (100); //-- 1.5.0 codeAs a matter of style, use the interface and not the real class when declaring a variable like the jobsList above whenever possible or applicable.
You do not need to cast the object newJob to Object. And you have inverted the positions of the parameters.
void add(int index, E element)
Inserts the specified element at the specified position in this list (optional operation).
jobsList.add(Index, newJob);
