hi, Here is my code
public class UserInterface extends Frame
{
public DefaultTableModel tableModel;
JScrollPane tablePane;
public JTable table;
String catTableName,catTableDescription;
Vector columnNames;
Vector catData,catAllData;
Vector vecCatData;
JScrollPane tableScroll;
public String findTicker,input;
Client c;
Socket s;
HashMap allTicker = new HashMap();
int rowCountdelete ;
/** Constructor
*/
public UserInterface()
{
setLayout(new BorderLayout());
Vector vecStockdata = new Vector();
Vector columnNames = new Vector();
String col1 ="Name";
String col2 ="Symbol";
String col3 ="Trade Market";
String col4 ="Last Trade Value";
String col5 ="52 weeks low";
String col6 ="52 weeks high";
columnNames.add(col1);
columnNames.add(col2);
columnNames.add(col3);
columnNames.add(col4);
columnNames.add(col5);
columnNames.add(col6);
int rowCount = 0;
int columnCount = 6;
tableModel =new DefaultTableModel(vecCatData,columnNames);
table = new JTable(tableModel);
TableColumn column = null;
for(int i = 0; i < 6; i++)
{
column = table.getColumnModel().getColumn(i);
if(i==0)
{
column.setPreferredWidth(200);
}
else if(i==1)
{
column.setPreferredWidth(30);
}
else
{
column.setPreferredWidth(50);
}
}
table.setPreferredScrollableViewportSize(new Dimension(900, 383));
tableScroll = new JScrollPane(table);
final JRadioButton addButton = new JRadioButton("Get");
final JRadioButton deleteButton = new JRadioButton("Delete");
JPanel radioPanel = new JPanel(new FlowLayout());
radioPanel.add(addButton);
radioPanel.add(deleteButton);
add(radioPanel, BorderLayout.SOUTH);
add(tableScroll,BorderLayout.CENTER);
public synchronized void getAllTableValue()
{
System.out.println("Coming inside method...");
int i;
Object tickRef = null;
Socket tableSocket = null;
int rowCount;
rowCount = table.getRowCount();
System.out.println("THE ROWCOUNT " + rowCount);
System.out.println("COUNT " + tableModel.getRowCount());
for(i=0;i<rowCount ;i++)
{
tickRef = table.getValueAt(i, 1);
String tickerRefresh = tickRef.toString();
System.out.println("Ticker for refreshing is " + i + "--" + tickerRefresh);
StockInfo sinfo = new StockInfo(tickerRefresh);
try{
tableSocket =new Socket(InetAddress.getLocalHost(),1167);
OutputStream ostable = (tableSocket.getOutputStream());
ObjectOutputStream oostable = new ObjectOutputStream(ostable);
oostable.writeObject(tickerRefresh);
InputStream istable = tableSocket.getInputStream();
ObjectInputStream iostable = new ObjectInputStream(istable);
sinfo = (StockInfo) iostable.readObject();
table.setValueAt(sinfo.getStockName(),i,0);
table.setValueAt(sinfo.getTicker(),i,1);
table.setValueAt(sinfo.getTradeMarket(),i,2);
table.setValueAt(sinfo.getLastTradeValue(),i,3);
table.setValueAt(sinfo.get52WeekLow(),i,4);
table.setValueAt(sinfo.get52WeekHigh(),i,5);
System.out.println("Table refreshed successfully...");
}
catch(UnknownHostException ue)
{
System.out.println("I can't find host");
}
catch(Exception ee)
{
System.out.println("Caught in exception");
System.out.println(ee.getMessage());
}
}
}
}
My Thread class code:
public class OurTableThread extends Thread implements Serializable
{
UserInterface uitable ;
public OurTableThread(){}
public OurTableThread(UserInterface uitable)
{
this.uitable = uitable;
}
public synchronized void run(){
while(true)
{
refresh();
}
}
public synchronized void refresh()
{
try{
uitable.getAllTableValues();
sleep(90000);
}
catch(InterruptedException ei){}
catch(NullPointerException ni){}
}
}
My Main program in which i am calling those to class:
public class OurClient
{
public static void main(String[] args) {
UserInterface ui = new UserInterface();
new OurTableThread(ui).start();
ui.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
ui.setSize(900, 300);
ui.setVisible(true);
ui.setTitle("Quote Server");
}
}
Here i pasted my part of UserInterface class and Main class...I can't put full code... I hope this will be understandable...Thanks.Expecting reply...
