Problems compiling when calling other classes

Question

hello,
following the Sun tutorial "How to build a application" i wrote this code...
package divelog;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class DiveLog extends JFrame{
     // make space in memory for a tabbed pane - not a object until constructor is called to initate
     private JTabbedPane tabbedPane;
     public DiveLog(){ //opens constructor - constructor iniaties objects
          super("Jason's DiveLog"); // super calls jframe - this is cause DiveLog extends JFrame
          addWindowListener(new WindowAdapter() // closes program form clicking "x" on the Jframe
          { //opens addWindowListener method
               public void windowClosing(WindowEvent e){
                    System.exit(0);
     tabbedPane = new JTabbedPane(SwingConstants.LEFT);
     //tabbedPane.setBackground(Color.blue);
     //tabbedPane.setForeground(Color.white);
     // method to add tabs
     populateTabbedPane();
     //method builds menu
     buildMenu();
     // put on JFrame and set sizes
     getContentPane().add(tabbedPane);
     pack();
     setSize(765,690);
     setBackground(Color.white);
     setVisible(true);
     } //ends constructor started on line 13  - DiveLog()     
     // Methods -- for the constructor
     private void populateTabbedPane(){
          tabbedPane.addTab("Welcome",
                                                            null,
                                                            new Welcome(),
                                                            "Welcome to Jason's Dive Log");
          tabbedPane.addTab("Diver Data",
                                                             null,
                                                             new Diver(),
                                                             "Click here to enter diver data");
          tabbedPane.addTab("Log Dives",
                                                            null,
                                                            new Dives(),
                                                            "Click here to enter dives");
          tabbedPane.addTab("Stats",
                                                            null,
                                                            new Statistics(),
                                                            "Click here to calculate stats");
     } // ends tabbed pane method
     private void buildMenu(){
          JMenuBar mb = new JMenuBar();
          JMenu menu = new JMenu("FIle");
          JMenuItem item = new JMenuItem("Exit");
          menu.add(item);
          mb.add(menu);
          setJMenuBar(mb);
          item.addActionListener(new ActionListener()
               public void actionPerformed(ActionEvent e){
                    System.exit(0);
     }// ends buildMenu method
} //ends class
          then... i made the welcome, dives,diver.... classes ...they look like this...
package divelog;
import javax.swing.*;
import java.awt.*;
public class Welcome extends JPanel{
}all the .java files are in /home/mohadib/java_restore/DiveLog/
so per the tutorial i try to compile with this.....
javac -classpath /home/mohadib/java_restore/ DiveLog.java
but i get this error....
mohadib@mohadib ~/java_restore/DiveLog--->javac -classpath /home/mohadib/java_restore/ DiveLog.java
DiveLog.java:48: cannot resolve symbol
symbol : class Welcome
location: class divelog.DiveLog
new Welcome(),
^
DiveLog.java:53: cannot resolve symbol
symbol : class Diver
location: class divelog.DiveLog
new Diver(),
^
DiveLog.java:58: cannot resolve symbol
symbol : class Dives
location: class divelog.DiveLog
new Dives(),
^
DiveLog.java:63: cannot resolve symbol
symbol : class Statistics
location: class divelog.DiveLog
new Statistics(),

4 errors

Answer 1

found the problem...
i used this at the top of all the .java files....
package divelog;
then my dir tree looked like this....
/home/mohadib/java_restore/DIveLog
so i changed to
/home/mohadib/java_restore/divelog
and compiled with this....
javac -classpath /home/mohadib/java_restore DiveLog.java
then ran it with this.....
java -classpath /home/mohadib/java_restore divelog.DiveLog
thanks,
jd
