public class recordsApplet
// Declare variables
String lstName;
String frstName;
Int socSec;
String street;
String city;
String state;
Int zip;
float rate;
Int numofdep;
//The buttons =
Button Submit = new Button("Add");
Button Change = new Button("Change");
Button Delete = new Button("Delete");
submit.addActionListner(this);
Change.addActionListener(this);
Delete.addActionListener(this);
//get input from users
System.out.println("Last Name:")
lstName = dataIn.readline();
System.out.println("First Name:")
frstName = dataIn.readline();
System.out.println("Social Security #:")
socSec = dataIn.readline();
System.out.println("Last Name:")
street = dataIn.readline();
System.out.println("Last Name:")
city = dataIn.readline();
System.out.println("Last Name:")
state = dataIn.readline();
System.out.println("Last Name:")
zip = dataIn.readline();
System.out.println("Rate of Pay:")
rate = dataIn.readline();
System.out.println("Number of Dependants:")
numofdep = dataIn.readline();
public void main(String[] args)
//store the information in a text file
try
output = DataOutputStream(new FileOutputStream("mocdb.txt"));
catch(IOException er)
system.exit(0)
//Print fields to text file
String arg = e.getActionCommand();
String code;
if (arg == "Submit")
code = "A";
elseif
code = "C";
else
code = "D";
try
output.writeUTF(code);
output.writeUTF(lstName.getText());
output.writeUTF(frstName.getText());
output.writeUTF(socSec.getText());
output.writeUTF(street.getText());
output.writeUTF(city.getText());
output.writeUTF(state.getText());
output.writeUTF(zip.getText());
output.writeUTF(rate.getText());
output.writeUTF(numofdep.getText());
catch(IOException c)
System.exit(1);
//Retrieve record from file
System.out.println("Last Name:")
lstName = dataIn.readline();
System.out.println("First Name:")
frstName = dataIn.readline();
try
record = new DataInputStream(new FileInputStream("mocdb.txt");
catch(IOException c)
system.exit(2)
//Check first and last name and get file
//Change data in file
//Delete the data in file
