Just a thought question here. In C++, I could do the following: vector<vector<string> > data; // add data into data //.. data[0].push_back( "somedata" ); And I would expect somedata to get written to the vector array because the [] notation gives me access to the object by reference. What about in Java? If I: List<List<String>> data = new ArrayList<List<String>>(); // add data into data //.. data.get(0).add( "somedata" ); Would this actually write somedata into the data object? Or would it create a new copy of the element at data(0), add somedata to that, and then that object disappears into GC sometime down the line?

Hello I need help creating 9 sub arrays of 3x3 dimensions from a 9x9 array. I've seen that stackOverflow had a similar question already asked but unfortunately it was in c++. Can anyone point me in the right direction of how to create a a sub array. Edit: had aa similar changed to had a similar public static void Validate(final int[][] sudokuBoard) { int width = sudokuBoard[0].length; int height = sudokuBoard.length; for(int i = 0; i < width; i++) if(!IsValidRow(sudokuBoard, i, width)) { System.out.print("(Row)" + i + " Error Detected \n"); //Do something - The row has repetitions } for(int j = 0; j < height; j++) if(!IsValidColumn(sudokuBoard, j, height)) { System.out.print(" (Column)" + j + " Error Detected \n"); //Do something - The columns has repetitions } // for(int i=0; i<3; i++) // if(!isBlock1Valid(sudokuB

I have an ordered array which looks like this:- [-0.0020057306590257895, 50, 0.09598853868194843, 50, 0.19398280802292264, 49.99999999999999, 0.2919770773638969, 50] What I would like to do is the following: Take each 'odd' entry and make it the 'key index in an object, which can be achieved by rounding the value and multiplying by 10 e.g. (Math.round(-0.0020057306590257895 * 10) should be index 0 and Math.round(0.09598853868194843 * 10) should be index 1 etc) Take the 'even' values and make them the corresponding values in the object. So... The above CSV file should return the following object:- { 0: 50, 1: 50, 2: 49.99999999999999, 3: 50 } Does anyone one know how I can parse this CSV to produce the required array using either jQuery or plain javascript?
