Thread: Ip pinging programm with tables, realy need help

Hello im stuck with my programm, I'm newbie at programming, but I have to finish this programm for my school project. I only use youtube tutorials, but in the end there is not enought info so im asking here for help.

Basicaly what this programm does is take ip addreses from Database and pings them, if it fails to ping it displays ip address in one table if pingable it dispalys in other.I hope you understand what im trying to do here, and plz don't say that my question is not clear, cause I dont think I can explain it better,its pretty hard cause I hardly understand programming language.


private void browseActionPerformed(java.awt.event.ActionEvent evt) {
JFileChooser chooser = new JFileChooser();
File F = new File ("c:/");
File NameDir, NamePath;
int Checker;
chooser.setCurrentDirectory(F);
chooser.setDialogTitle ("Choose db");
Checker = chooser.showOpenDialog(null);

if (Checker == JFileChooser.APPROVE_OPTION){
NameDir = chooser.getCurrentDirectory();
NamePath = chooser.getSelectedFile();

try {

Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

String filename = NamePath.getAbsolutePath();
String database = "jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=";
database+= filename.trim() + ";DriverID=22;READONLY=true}";
Connection con = DriverManager.getConnection( database ,"","");

//I am using Access Database thats why all this connection code ^^

Statement s = con.createStatement();
s.execute("SELECT AgIP FROM Agents ");
ResultSet rs = s.getResultSet();
if (rs != null)
while ( rs.next()){
String sampleString = rs.getString(1);
boolean reachable = false;
reachable=(InetAddress.getByName(sampleString).isR eachable(1000));

if (reachable==true){
for (int i = 0;i <jTable1.getRowCount();i++){ //This place is not right for sure
jTable1.getModel().setValueAt(sampleString, i, 0);

}
}
else{


for (int e = 0;e <jTable2.getRowCount();e++){
jTable2.getModel().setValueAt(sampleString, e , 0);

}
}
}
}
catch (Exception err) {
System.out.println("ERROR: " + err);
}
}
}

Hope it is enough info.In picture I added there is explained deeper what im trying to achieve.

Anyone?

Use official Oracle tutorial. It has more than enough info for you to understand Java and Swing.

What exactly is wrong with it?

There is no need to "bump" your thread. The volunteers will read it when they get to it and bumping your thread does not cause anyone to sit down at their pc any sooner. However, it does cause extra for us to read and reply to, which actually decreases the amount of help provided over time.

I understand what you want the code to do. I do not understand where you are stuck or what problem you are having. Does the code compile? Are there any error messages? What were you trying to accomplish (specifically what step are you on in the overall project) when you got stuck?
