Step 1 Employee class
=====================
Fields:
    private String name;
    private int salary;
    private int annualLeaves;

Constructor, getName, addSalary:
    public Employee(String n, int s, int al) {
        name=n; salary=s; annualLeaves=al;
    }

    public String getName() {return name;}

    public void addSalary(int inc) {salary+=inc;}

toString:
    @Override
    public String toString() {
        return _________ + " ($"+_________+", "+_________+" days)";
     }
}



Step 2 Company class
====================
[See lab sheet]



Step 3 main
===========
[1] Given framework

import java.io.*;
import java.util.*;

public class Main {

	public static void main(String [] args) throws FileNotFoundException
	{	
		
	}
}


[2] Read file pathname + file opening

	Scanner in = new Scanner(System.in);
	System.out.print("Please input the file pathname: ");
	String filepathname = in.nextLine();
	Scanner inFile = new Scanner(new File(filepathname));
	..
	.. PLEASE add the code from [3]: (i) store employee data and (ii) process commands
	..
	inFile.close();			
	in.close();
	
		
[3] Read file contents (i) store employee data, (ii) process commands
	int tot=inFile.nextInt();
	Company company = Company.getInstance();
	for (int i=0;i<tot;i++) 
		company.addEmployee(new Employee(inFile.next(),inFile.nextInt(),inFile.nextInt()));
			
	while (inFile.hasNext())		
	{
		String cmdLine = inFile.nextLine();
		
		//Blank lines exist in data file as separators.  Skip them.
		if (cmdLine.equals("")) continue;  
		
		System.out.println("\n> "+cmdLine);
		
		//split the words in actionLine => create an array of word strings [!!! LEARN !!!]
		String[] cmdParts = cmdLine.split(" "); 
		
		if (cmdParts[0].equals("addSalary"))
			(new AddSalary()).execute(cmdParts);
		if (cmdParts[0].equals("list"))
			(new ListAllRecords()).execute(cmdParts);
	}



Step 4 Command interface, AddSalary class, ListAllRecords class
