java project help, reading in from a file and adding data to JTable

Question

Hey guys iv got this project to make an address book that has all kinds of functions and iv got them all working apart from one bit, it needs to be able to read a file when it opens as well as import other data from other files.

The data comes in the following format:
Tony Hancock
01202719029
07676101393
1 Charminster Road, Bournemouth, Dorset, BH8 8UE
Auberon Waugh
01823810098
None
Combe Florey House, Combe Florey, Somerset, TA4 3JD

so name, home number, mobile number and then address.

i have been trying to bufferedread the file in and then add the details to an arrayList which i then need to set up a loop to catch the first index which would be the name then link that to the Jtable name section (textFirstName and textLastName) somehow, then repeat that for another 3 index's till index 3 and start again, BUT how do i do that????

any help would be great guys, im so close to finishing and got very little time left.

Thanks

heres my code so far:

public class Q3 implements ActionListener
{
	
   	JFrame addressBook;   	
   	JFrame contacts;
   	JList theList;
   	DefaultTableModel tableModel;

You should have successfully read the file into the arraylist in the lines 349 - 359.
You now need to separate the lines into groups of four which are the formatted into contact records.
The loop will need to run upto the size of the array, so use

for(int i=0;fileRead.size();i+=4)

You will need to split fileRead into two strings for firstname and lastname
then set

textPhone=fileRead[i+1];
textMob=fileRead[i+2];
textAddress=fileRead[i+3];
contact a = new a contact(textFirstname,textLastname,textPhone,textMob,textAddress);
people.add(a);

You will also need to add the values to the tableModel as per the code commented out.

The problem here is variable typing and I should have checked the type before writing the previous section. You have an ArrayList of strings read in from the file and need to form these into contact objects. Each contact object contains five strings for the record, but you have a number of sets of four strings apiece, the first and last names are combined in the file. You cannot put the strings into JTextFields and so get an error, nor do you want to. You need string variables at this point so create some;

String firstName,lastName,telephone,mob,address;
int space; //used later

then we can assign the ArrayList contents to these

telephone=fileread[i+1];
mob=fileread[i+2];
address=fileread[i+3];

However, we still have to split the first line fileread, I presume you should have been shown String.indexOf() has you need this or something similar to split the String!
Assuming the names consist of only first and last names with both names being single words you can look for the separating space.

firstname=fileread[i];
space=firstname.indexOf(" ");
lastname=firstname.substring(space);
firstname.firstname.substring(0,space);
a=new contact(firstname,lastname,telephone,mob,address);

There are other arguably better ways to do this but this should work.

Thanks so much for your help steve, im still having afew problems tho, on line 397-399 it is saying that the type of expression must be an array type but it resolved it to an arrayList, iv tried changing it from an arrayList to an array but i just get more errors, any idea why?

this is my new section of code....

public void readFromFile () throws Exception
   	{
   		// open file with bufferedreader
   		// while ()
   		//   check 
   		// counter....... number of lines per contact is 4, name,home number, mobile number, address.
   		
   		ArrayList<String> fileRead = new ArrayList<String>();
   		
   		try 
   		{
   			String lineread = "";
   			
   			
   			BufferedReader bufferedReadIn = new BufferedReader(new FileReader("H:\\Copy of address book//a.txt"));
			while ((lineread = bufferedReadIn.readLine()) != null)
			
			{
				fileRead.add(lineread);
				for  (int i = 0; i < fileRead.size(); i+=4)
				{
					textPhone = fileRead [i +1];
					textMob = fileRead[i +2 ];
					textAddress = fileRead[i+3];
				}	
					
					contact a = new contact(textFirstName.getText(), textLastName.getText(),textPhone.getText(), textMob.getText(), textAddress.getText());
		   			people.add(a);
					
					
					
				
					
				
			}
			System.out.println(fileRead.get(0));

still having afew problems mate, it doesnt seem to want to use the indexs to get the data.
where i try and assign the data in the indexs to the strings it is still saying "the type of the expression must be an array type but it resolved to an ArrayList<String>

i tried using the .get but that doesnt seem to work, i dont know if im just being really stupid but im bagging my head against the wall atm.

public void readFromFile () throws Exception
   	{
   		// open file with bufferedreader
   		// while ()
   		//   check 
   		// counter....... number of lines per contact is 4, name,home number, mobile number, address.
   		
   		ArrayList<String> fileRead = new ArrayList<String>();
   		
   		try 
   		{
   			String lineread = "";
   			
   			BufferedReader bufferedReadIn = new BufferedReader(new FileReader("H:\\Copy of address book//a.txt"));
			while ((lineread = bufferedReadIn.readLine()) != null)
			
			{
				fileRead.add(lineread);
				
				for  (int i = 0; i < fileRead.size(); i+=4)
				{
					telephone = fileRead[i+1];
					mob2 = fileRead.get(i+2);
					address2 = fileRead.get(i+3);
					firstName = fileRead.get(i);
					space = firstName.indexOf(" ");
					lastName = firstName.substring(0, space);
					
				}	
				
			}
			contact a = new contact(firstName, lastName, telephone, mob2, address2);
			//System.out.println(address);
			
			//System.out.println(fileRead.get(0));
						
			//contact a = new contact(textFirstName.getText(), textLastName.getText(),textPhone.getText(), textMob.getText(), textAddress.getText());
   			//people.add(a);
   			
   			//this.tableModel.addRow(new Object[]{a.getFirstName() + " " + a.getLastName(),a.getAddress(),
   					//a.getHomeNumber(), a.getMobileNumber()});
			
			//System.out.println(a);

			bufferedReadIn.close();
   			
		}	
		
		catch (IOException ex)
		{
			System.out.println("error");
		}
   		
   	}

lines 22-25 are the problem atm

think i may have worked out them problem, i have got the name part displaying as long as i comment out the address and phone number parts of the for loop, could it be something to do with the for declaration?? the indexs not being right?
