New to Java

I am having problems with the following code. Can anyone help?

//CheckPoint: Payroll Program Part 3
//Payroll3.java
//Payroll program that calculates the weekly pay for an employee. 
 
import java.util.Scanner; // program uses class Scanner
 
public class Payroll3
{
   // main method begins execution of java application
   public static void main( String args[] )
   {
     private string name;
     private float rate;
     private float hours;
     
     // Constructor to store Employee Data
 
     public void Payroll3( string nameOfEmployee, float hourlyRate, float hoursWorked )
     {
          name = nameOfEmployee;
          rate = hourlyRate;
          hours = hoursWorked;
     
     } // end constructor
} //end class EmployeeData
 

      System.out.println( "Welcome to the Payroll Program! " );
      
      
      boolean quit = false; // This flag will control whether we exit the loop below
 
      // Loop until user types "quit" as the employee name:
      while (!quit)
      {     
       // create scanner to obtain input from command window
        Scanner input = new Scanner ( System.in );
     
        
        System.out.println();  // outputs a blank line
        System.out.print( "Please enter the employee name or quit to terminate program: " );
        // prompt for and input employee name
        String nameOfEmployee = input.nextLine(); // read what user has inputted
       
        
        if ( nameOfEmployee.equals("quit")) // Check whether user indicated to quit program
        {
          System.out.println( "Program has ended" );
          quit = true;
        }
 else
 {
          // User did not indicate to stop, so continue reading info for this iteration:
          float hourlyRate; // first number to multiply
          float hoursWorked; // second number to multiply
          float product; // product of hourlyRate and hoursWorked
 
          System.out.print( "Enter hourly rate: " ); // prompt 
          hourlyRate = input.nextFloat(); // read first number from user
 
          
          while (hourlyRate <= 0) // prompt until a positive value is entered
          {
             System.out.print( "Hourly rate must be a positive value. " +
               "Please enter the hourly rate again: " ); // prompt for positive value for hourly rate
              hourlyRate = input.nextFloat(); // read first number again
          }
 
          System.out.print( "Enter hours worked: " ); // prompt 
          hoursWorked = input.nextFloat(); // read second number from user
 
          
          while (hoursWorked <= 0) // prompt until a positive value is entered
          {
             System.out.print( "Hours worked must be a positive value. " +
               "Please enter the hours worked again: " ); // prompt for positive value for hours worked
              hoursWorked = input.nextFloat(); // read second number again
          }
 
          product = (float) hourlyRate * hoursWorked; // multiply the hourly rate by the hours worked
 
          // Display output for this iteration
          
          System.out.println(); // outputs a blank line
          System.out.print( nameOfEmployee ); // display employee name
          System.out.printf( "'s weekly pay is: $%,.2f\n", product);  // display product
          System.out.println(); // outputs a blank line
          
        }
      }
     
      // Display ending message:
      System.out.println( "Thank you for using the Payroll program!" );
      System.out.println(); // outputs a blank line
   
   } // end method main
 
} // end class Payroll3

I have the following errors

Payroll3.java:25: 'class' or 'interface' expected
public static void main( String arg[] )
___________^

Payroll3.java:97: 'class' or 'interface' expected
} // end class Payroll3

Payroll3.java:97: 'class' or 'interface' expected
