Multiple lines in arrayList

[Lund01]

I have a little bit problems with putting multiple lines in an arrayList.
The arrayList works, but he only takes 1 line in it.
And I would like the arrayList to take all the lines in the file.

 
			// Create Scanner for file1.
			// file1 bezit alleen de query= codes.
			Scanner x = new Scanner(file1);

			// We read the lines one by one in the file.
			if (x.hasNextLine()) {
				String line = x.nextLine();

				// We put what is in file1 into an arrayList.
				arrayList.add(line);

			}

Lund01,

The if statement is only being evaluated once so will only execute the code once.
Use a while loop instead.

You keep asking this question.
I answered elsewhere...you are only reading one line and inserting one line.
You need a loop!

I did use a while loop first.
But the he read the 2nd file also 2 times.

I it possible to put this while loop in another class?
This one from arrayList.

What?
this is your code:

// Create Scanner for file1.
			// file1 bezit alleen de query= codes.
			Scanner x = new Scanner(file1);

			// We read the lines one by one in the file.
			[B]if [/B](x.hasNextLine()) {
				String line = x.nextLine();

				// We put what is in file1 into an arrayList.
				arrayList.add(line);

			}

Why can you not simply:

// Create Scanner for file1.
            // file1 bezit alleen de query= codes.
            Scanner x = new Scanner(file1);

            // We read the lines one by one in the file.
            [B]while [/B](x.hasNextLine()) {
                String line = x.nextLine();
                // We put what is in file1 into an arrayList.
                arrayList.add(line);
            }

That will read each line (though I would use a BufferedReader, I hate Scanner for simple file reading) and stick it in an array.

This is funny....

I first removed the while and made it an if, becose he also read the 2nd file two times. And that worked, he only read the 2nd file 1 time. And I just tried making the if to a while again. And now he reads it all into the arrayList. But the funny part is, he now also reads file2 only 1 time. While I haven't adjusted anything else. :confused:

So it all works, but now for me to figure out why he first read file2 2 times. And now he doesn't anymore.

That code is reading one file and one file only...file1.
There is nothing in that code there involving a second file.
