    <p>I am trying to create a program that generates chutes and ladders onto 2D array board that is of size 10X10. In order to generate these chutes and ladders, I had to create a method called <code>readBoard</code> that basically reads a written file (myBoard.csv) and translates the written information into positions and place the chutes and ladders onto the 2D array board accordingly. </p> <p>The program compiles but when I run it there is this error:</p> <p><code>java.lang.ArrayIndexOutOfBoundsException: 1 at ChutesAndLadders.readBoard(ChutesAndLadders.java:41) at TestFile.main(TestFile.java:13) </code> My impression was that perhaps my written file had additional spaces that I didn't see that's why it's telling me I'm out of bound. However, I checked the written file and it looks fine. If you could provide some insight into this problem, that would be great. Thanks in advance! </p> <p>Here is my <code>getBoard</code>method:</p> <pre><code>public void readBoard(String filename)throws Exception { Scanner s=new Scanner(new File(filename)); s.nextInt(); while (s.hasNext()) { String line=s.nextLine(); String[]singleSplit=line.split(","); String cellType=singleSplit[0]; int row=Integer.parseInt(singleSplit[1]); int col=Integer.parseInt(singleSplit[2]); if (cellType.equals("Chute")) board[row][col]=new Chute(); else board[row][col]=new Ladder(); } } </code></pre> <p>and here is my written file (type,row,column):</p> <p>29</p> <p>Chute,1,0</p> <p>Chute,2,0</p> <p>Chute,3,0</p> <p>Chute,4,0</p> <p>Chute,5,0</p> <p>Chute,6,0</p> <p>Chute,7,0</p> <p>Chute,8,0</p> <p>Chute,9,0</p> <p>Chute,0,1</p> <p>Chute,0,2</p> <p>Chute,0,3</p> <p>Chute,9,1</p> <p>Chute,9,2</p> <p>Chute,9,3</p> <p>Ladder,0,5</p> <p>Ladder,1,5</p> <p>Ladder,2,5</p> <p>Ladder,3,5</p> <p>Ladder,4,5</p> <p>Ladder,5,5</p> <p>Ladder,6,5</p> <p>Ladder,7,5</p> <p>Ladder,8,5</p> <p>Ladder,9,5</p> <p>Ladder,9,6</p> <p>Ladder,9,7</p> <p>Ladder,9,8</p> <p>Ladder,9,9</p>

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.
