    <p>I have extended a class in hope to store a global array (make the array within the class be seen by another object) by using the set1sub(sub.local) method</p> <pre><code>public class BattleShipsClient extends ShipLocations implements Runnable, BattleShipConstants { BattleShipsClient() { } public void placeBoard(int player) throws IOException// this is only called once and not updated when clicked again { while(getLocations()) { while(isWaiting())//true { toServer.writeInt(player); int row = getRowSelected(); int col = getColumnSelected(); int choice=Integer.parseInt(JOptionPane.showInputDialog("Please 1 for a sub, 2 for a battleship and 3 for a destroyer")); clickCount ++; if(clickCount &gt;2) { setLocation(false); continueToPlay=true; } if (choice ==1 &amp;&amp;sub.placed==false) { String orientation =JOptionPane.showInputDialog("please enter your orientations"); if(orientation.equalsIgnoreCase("h")) { //row os the same //column number will be sent, then plus one on the other side sub.local = new int[2][2]; sub.local[0][0] =row; sub.local[0][1]=col; sub.local[1][0]=row; sub.local[1][1] =col+1; toServer.writeInt(row); toServer.writeInt(col); toServer.writeChar('s'); sub.placed=true; setp1sub(sub.local); /*setp1sub(new int[][]{{row,col}, {row,col+1}});*/ grid[row][col+1].setToken(getMyToken()); } </code></pre> <p>I then have a ship Locations class however when i create a new object of the ship locations class and try to read this array it always is set to [[0, 0], [0, 0]], ive tried making it static and atomic</p> <pre><code>public class ShipLocations { int [][] p1sub; public ShipLocations() { p1sub = new int[2][2]; } public int[][] getp1sub() { return p1sub; } public void setp1sub(int[][] local) { for (int i = 0;i &lt;local.length;i++) { for(int j = 0;j&lt;local.length;j++) { p1sub [i][j]= local[i][j]; } } } } </code></pre>

    1. COHow are you verifying the array is not changed? have you tried debugging? Seems to me the `ShipLocations` code is correct.

    2. CO@Ivaylo in a GameSession class i create a new shiplocations object then call it by `if(sl.p1sub==null){System.out.println("array is null");} System.out.println(Arrays.deepToString(sl.getp1sub())); `

    3. COwhat you say here significantly differs from your question. Is your array always `{{0,0},{0,0}` or is it always `null`?

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.
