Java understanding:

What this code is and how it works

What does the while(x < n) mean

then try and catch explain

read.useDelimiter(" "); //returns the scanner object/setting the pattern int x = 0; while(x < n) { String[] data = read.next().split( regex: ","); //reading the input try{ letter2DS [x] = new Letter2D (Integer.parseInt(data[0]), Integer.parseInt(data[1]), (data[2].charAt(0))); x++; }catch (Exception ignored) { } } return letter2DS;
