I am having a little trouble with classes

Question

I can not figure out what is wrong or missing from this code because I keep getting "declare in file" error code
this is the simple code
import java.util.Scanner; //program uses class Scanner
import java.text.NumberFormat;//used to format currency
import java.util.Locale;
public class Employee
public Employee();
//main method begins execution of Java application
//create Scanner to obtain input from command window
Scanner input=new Scanner (System.in);
//varibles declared
String Emp_name;//Stores employee name
double Hours_worked;///Stores hours worked
double PayRate;//Stores PayRate
System.out.print("Enter Employee;s name:");//prompt
Emp_name=input.nextLine();//read employee's name entered
System.out.print("Enter the pay rate of the Employee:");//prompt
PayRate=input.nextDouble();//read the payrate of employee
System.out.print("Enter the Employee's Hours worked:");//prompt
Hours_worked=input.nextDouble();//read hourlyrate of pay entered by user
NumberFormat nf=NumberFormat.getCurrencyInstance(Locale.US);
System.out.printIn("Employee" + Emp_name);//display employee_Name
System.out.printf("Employee's Pay: $" +nf.format(Hours_worked*PayRate));//display GPA
}

masterbuild,
Firstly, post your code between code tags.
[code]... your code goes here ...[/code]
so it looks like thisdouble check it using preview before you commit the post.
Now, Please don't be offended, That's not a bad first try, but it's just all wrong, which is part of the learning process.
Here's a list the problems I can see with that code, and what to do about them... if you address these problems you should end up with a working program.
Number 1
public class Employee
public Employee();
//main method begins execution of Java application
{As The Pair of Condiments and The Sick Brainiac have already stated... lose the semicolon!... it should look like this...
public class Employee
  public Employee() {
Number 2
//main method begins execution of Java application
What main method? I don't see any main method... Where's your main method? It should look like this
  public void main(String[] args) {
    Scanner input = new Scanner(System.in);
    System.out.print("employee's name : ");
    String name = input.nextLine();
    System.out.print("hourly rate : ");
    double hourlyRate = input.nextDouble();
    System.out.print("hours worked : ");
    double hoursWorked = input.nextDouble();
    System.out.printf("%s's gross pay is $%s\n", name, NUMBER_FORMATTER.format(hoursWorked*hourlyRate));
  }* The convention is to use camelCase (hump in the middle) for variable names, and CapitalCase for class names. See http://java.sun.com/docs/codeconv/
Number 3
The numberFormatter would best be declared as a class attribute, so you can reuse whenever you print a currency amount... as in...
public class Employee
  private static final NumberFormat NUMBER_FORMATTER = NumberFormat.getCurrencyInstance(Locale.US);
  public Employee() {
    ....Also... these three comments worry me a bit...
// Stores employee name
// Stores hours worked
// Stores PayRate
None of these values are being "stored". These three values are local variables, which exist only while the method (actually block) in which they are declared is executing... after that they are "forgotten". To a programmer the word "store" implies that the values are being persisted in a file, or database... that is the values are being stored in any fashion for reuse by a subsequent execution of this program, or indeed another program. I think it's just that you don't know the lingo yet, but I just wanted to be sure that you know that these values will be forgotten as soon as the main method is finished.
Cheers. Keith.
