What's the logic error in this piece of code?

Question

Hello All:
I am doing a simple program dealing with restaurant operation. The problem is that when customer click check out button, the status of the corresponding table object doesn't change to "Vacant", whereas it should as according to my design.
Following is the piece of code from the Interface class, where check out button (outB) is declared and add with an ActionListener:
pCentre.setLayout(new GridLayout(3,2));
     outL = new Label("Pls type your table number to check out");
     outTable = new TextField(30);
     outMsg = new TextField(30);
     outB = new Button("Check Out");
     outB.addActionListener(new ActionListener(){
          public void actionPerformed(ActionEvent e)
          int tbNo = Integer.parseInt(outTable.getText());
          if (tbNo<1 || tbNo>5)
               outMsg.setText("This table doesn't exist!");
          else
               outMsg.setText("Thank you. See you again.");
proc.checkout(tbNo);
          }// proc is the handler of Processor Class, which contain the checkout method.
this is Processor class:
public class Processor
DataStore ds;
public Processor()
ds = new DataStore();
public int searchTable(CusmInfo ci)
for (int i=0; i<5; i++)
     if((ds.tInfo.tCap > ci.cNo) &&
     (ds.tInfo[i].tStat.equals("Vacant")))
     ds.tInfo[i].tStat = ci.name;
          return i+1;
     return -1;
     public String check(int i)
     if(i<1 || i>5)
     return("Table number exceeded");
else
     return ds.tInfo[i-1].tStat;
public void checkout(int i)
     ds.tInfo[i-1].tStat = "Vacant";     
This is DataStore class which caters for table objects:
public class DataStore
public TableInfo[] tInfo = new TableInfo[5];
public DataStore()
tInfo[0] = new TableInfo(1, 4, "Vacant");
tInfo[1] = new TableInfo(2, 4, "Vacant");
tInfo[2] = new TableInfo(3, 6, "Occupy");
tInfo[3] = new TableInfo(4, 6, "Occupy");
tInfo[4] = new TableInfo(5, 8, "Vacant");
public TableInfo getTableInfo(int i)
return tInfo[i];
class TableInfo
int tNo;
int tCap;
String tStat;
public TableInfo(int n, int c, String s)
tNo = n;
     tCap = c;
     tStat = s;
Why is it that after clicking the outB button, the status of the table is still customer's name but not "vacant". It seems the checkout method doesn't work. Is it because we can change the attribute of table object directly? BTW, the rest of methods in Prossor class all work properly.

Lol, "piece" of code is good...
First, you should encapsule your code in "code" tags ([_code_] and [_/code_] w/o the underscores) so it will be much more readable.
Then maybe you should assign some dukedollars to attract people to do the work for you. This is not an easy one-minute-thought question like "I'm new to java how do i print out text to stdout?" ....
Do that and I'll check back to have a look...
