Lab 8 Hints and Tips

Part 1

• In Step 3, you need to create a scanner and read TWO lines of text. The first line contains the text you will write to the file and second line is the file name.
• In Step 3c, your code might look like (assuming you stored the file-name string in a variable named fileName):

  File theFile = new File(fileName);
  if(theFile.exists())
     System.out.println("Warning: File exists, overwriting");
          

• In Step 3d, your code might look like:

  BufferedWriter bw = new BufferedWriter(new FileWriter(fileName));
  bw.write(theText);
  bw.close();
          

  Note that you will need to handle exceptions!

Part 2

• In Step 2, your fields might look like:

  private String firstName;
  private String lastName;
  private String address;
  private String address2;
  private String city;
  private String state;
  private String zip;
  private String phone;
        

• In Step 7, the code your parseCSVLine() method should create an Address object, split the input line into substrings, splitting on the comma, and then initialize the Address object and return it. Here's some code to help you get started (you will need to complete it):

  Address theAddress = new Address();
  		
  String[] fields = line.split(",");
  		
  theAddress.setFirstName(fields[0]);
  theAddress.setLastName(fields[1]);
  . . .
  
  return theAddress;
        

• In Step 8, substep 1, you can create an ArrayList:

  ArrayList<Address> theList = new ArrayList<>();
