How to get to a particular element in a List in java?

Question

The List interface supports random access via the get method - to get line 0, use list.get(0). You'll need to use array access on that, ie, lines.get(0)[0] is the first element of the first line.

See the javadoc here.

The toString method of array types in Java isn't particularly meaningful, other than telling you what that is an array of.

You can use java.util.Arrays.toString for that.

Or if your lines only contain numbers, and you want a line as 1,2,3,4... instead of [1, 2, 3, ...], you can use:

java.util.Arrays.toString(someArray).replaceAll("\\]| |\\[","")

At this point:

for (String[] s : myEntries) {
   System.out.println("Next item: " + s);
}

You need to join the array of Strings in a line. Check this post: A method to reverse effect of java String.split()?
