How to iterate through an Array of objects and a file at the same time?

[Adam Cripps]

I have a scenario where I have an Array of CurriculumSubject objects (which in turn has creted 15 JTextField object instances) and then a text file.

I want to iterate through the CurriculumSubject Array (and each JTextField for each subject) and go through the text file line by line, setting each JTextField to one line - and then move on to the next.

Currently, I have this method which receives a File object:

	public void setItemsFromFile(File contents){
		ListIterator textfieldsIter = subjectList.listIterator(); 
		while(textfieldsIter.hasNext()){		
			CurriculumSubject subject = (CurriculumSubject) textfieldsIter.next();
			for (int i =0; i<15; i++){
				subject.textfields[i].setText("testing" + subject.getName()); //I need a file from a line here. 
			}
			
		}
	}

How can I integrate a BufferedReader in to this so that as I move through the 15 JTextFields, the BufferedReader reads the next line of the file?

TIA

Why do you need a reader for text fields? Can’t you use their getText() method?

Campbell misunderstood. i see what you want to do. set the texFields from info in the file. if someone doesn't answer first i'll see if i can find something like that.
i havent read this but it seems like what you want
read file

Thanks Randall - you are correct. The BufferedReader is to handle the text file and go through the file line by line. I already have managed to access the JTextFields through set and get, so that part of the problem is sorted - it's reading the file line by line that I really need help with. Thanks.

Well BufferedReader.readLine() returns the next line if there is one; or null if there isn't. Maybe that'll help.

Thanks Winston. However, I will need to iterate through the file - how do I knit the two iterations together?

I suggest you have a think about it and try something yourself. I've already given you all the information you need to write a read loop of your own using either for or while.

so true. often i post questions here and then after i think about it, i come up with the answer.
