Body
as far as I saw in your comment you would like to have also an 2D array with boolean if the character is 'X' so I filled two arrays in my code - one actually with the character and one with true or false, depending of the character is 'X' or not. There are also some system.outs to better understand how it works. I am removing newline characters ('\n') when appearing (dont know if you want that or not) <pre><code>public static void main(String[] args) { final int cellSize = 30; // grid size char[][] chargrid = new char[cellSize][cellSize]; boolean[][] chargridIsX = new boolean[cellSize][cellSize]; File inputFile = new File("input.txt"); FileInputStream is = null; try { is = new FileInputStream(inputFile); int n = -1; int rowCount = 0; int colCount = 0; while( (n=is.read()) !=-1){ char readChar = (char) n; if(readChar!='\n'){//This removes the linebreaks - dont know if you want that chargrid[rowCount][colCount] = readChar; if(readChar=='X') { // Here actually set true or false if character is 'X' chargridIsX[rowCount][colCount] = true; System.out.println("row "+rowCount+" col "+colCount + " = " + readChar + " " + true); }else { chargridIsX[rowCount][colCount] = false; System.out.println("row "+rowCount+" col "+colCount + " = " + readChar+ " " + false); } if(rowCount++ >= cellSize-1){ System.out.println("new col"); rowCount = 0; if(colCount++ >= cellSize-1){ //ARRAY IS FULL System.out.println("full"); break; } } } } } catch (FileNotFoundException e) { //could not get Inputstream from file e.printStackTrace(); } catch (IOException e) { // problem with the inputstream while reading e.printStackTrace(); } </code></pre> btw. I am reading character for character from an inputstream instead of using scanner, hope that is okay - otherwise let me know For what ever this might be good

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
