cannot resolve symbol

[Mulugeta Maru]

The error message I am getting is that of cannot resolve symbol. I have to class as show below and when I try to compile ClickMe.java I get the error message:

clickme.java:6: cannot resolve symbol
symbol : class Spot
location: class ClickMe
private Spot spot = null;

clickme.java:28: cannot resolve symbol
symbol : class Spot
location: class ClickMe
spot = new Spot(RADIUS)
2 errors

public class Spot {
    public int size;
    public int x, y;
 
    public Spot(int intSize) {
        size = intSize;
        x = -1;
        y = -1;
    }
}

import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
 
public class ClickMe extends Applet implements MouseListener {
    private Spot spot = null;
    private static final int RADIUS = 7;
 
    public void init() {
addMouseListener(this);
    }
 
    public void paint(Graphics g) {
//draw a black border and a white background
        g.setColor(Color.white);
g.fillRect(0, 0, getSize().width - 1, getSize().height - 1);
        g.setColor(Color.black);
g.drawRect(0, 0, getSize().width - 1, getSize().height - 1);
 
//draw the spot
        g.setColor(Color.red);
if (spot != null) {
    g.fillOval(spot.x - RADIUS, spot.y - RADIUS, RADIUS * 2, RADIUS * 2);
        }
    }
    public void mousePressed(MouseEvent event) {
        if (spot == null) {
            spot = new Spot(RADIUS);
        }
spot.x = event.getX();
spot.y = event.getY();
repaint();
    }
    public void mouseClicked(MouseEvent event) {}
    public void mouseReleased(MouseEvent event) {}
    public void mouseEntered(MouseEvent event) {}
    public void mouseExited(MouseEvent event) {}
}

Please note that I have no problem compiling a single class i.e. a class that does not refere to another class.

It is my understanding that when I compile ClickMe it automatically compiles Spot.

Thank you for you help.

It's most likely a classpath issue. It looks like you're not putting these classes in a package, so it should be as simple as making sure that the current directory (".") is part of the class path. Then you do the compile (javac) and execute (java) commands in the directory where the source is located.

You can add "." to the classpath as part of the environment, or you can explicitly specify it using the "-cp" or "-classpath" flags.

There are thousands of web sites where you can get details on how to set up the classpath, and I'm sure there is a link here at JavaRanch that describes it as well. I'll see if I can find a good one and add it to this post.

I am not sure my CLASSPATH is properly set.

REM C:\SAMSUNG\MSCDEX /D:SSCD000
C:\SAMSUNG\MSCDEX /D:SSCD000
 

set PATH=%PATH%;F:\j2sdk1.4.2_04\bin
set JAVA_HOME=F:\j2sdk1.4.2_04
set CLASSPATH=.;F:\"."
 
set CATALINA_HOME=F:\Tomcat5_0
set CLASSPATH=%CLASSPATH%;%CATALINA_HOME%\common\lib\servlet-api.jar
set CLASSPATH=F:\Tomcat5_0\webapps\ATS\WEB-INF\classes;%CLASSPATH%
 
set JBOSS_HOME=F:\JBOSS-3.2.3
set CLASSPATH=%CLASSPATH%;%JBOSS_HOME%\server\default\lib\javax.servlet.jar;%JBOSS_HOME%\MARU\WEB-INF\classes
 

set PATH=%PATH%;F:\Ant\bin
set ANT_HOME=F:\Ant

set CLASSPATH=\path\to\mysql-connector-java-3.0.11-bin.jar;%CLASSPATH%

Yes it is a CLASSPATH problem.I made changes to the CLASSPATH and it now works perfectly.

Thank you for your kind help.
