Message:
Importing Packages
Posted by Wilma on September 28, 2001 at 7:35 AM
I�m new to Java programming and have no C++
background. I'm having real trouble with packages and
was wondering if anybody could help me. This
is an example I�m working with from the book: "Thinking in Java" by Bruce Eckel I created 2 classes named Vector and List who are both
part of the com.bruceeckel.Util package: package com.bruceeckel.Util; public class Vector
{
public Vector()
{
System.out.println("com.bruceeckel.util.Vector");
}
} package com.bruceeckel.Util; public class List
{
public List()
{
System.out.println("com.bruceeckel.util.list");
}
} I saved them both on c:\JavaOef\com\bruceeckel\Util as
Vector.java and List.java. I compiled them and there
was no problem. (It created the *.class files) Then I created this class that is in a different
package (c05). This class will use the other two to
compile and then � hopefully � run: package c05;
import com.bruceeckel.Util.*; public class LibTest
{
public static void main(String args[])
{
Vector v = new Vector();
List L = new List();
}
} I saved this class on c:\JavaOef\c05 as LibTest.java When I try to compile this class I get the following
errors: LibTest.java:2: package com.bruceeckel.Util does not
exist
import com.bruceeckel.Util.*;
^
LibTest.java:8: cannot resolve symbol
symbol : class Vector
location: class c05.LibTest
Vector v = new Vector();
^
LibTest.java:8: cannot resolve symbol
symbol : class Vector
location: class c05.LibTest
Vector v = new Vector();
^
LibTest.java:9: cannot resolve symbol
symbol : class List
location: class c05.LibTest
List L = new List();
^
LibTest.java:9: cannot resolve symbol
symbol : class List
location: class c05.LibTest
List L = new List();
^
5 errors I suspect that there is a problem with my saving -
one book I have talks about a CLASSPATH, but how does
that work. I�ve tried to import the package, but I
still get errors. Please, if you could help me, I would appreciate it
very much.
