creating package

[Pradyut]

I have two files: -

------------------Alpha.java--------------------------------------------------
package One;
public class Alpha {
//member variables
private int iamprivate = 1;
int iampackage = 2; //package access
protected int iamprotected = 3;
public int iampublic = 4;

//methods
private void privateMethod() {
System.out.println("iamprivate Method");
}
void packageMethod() { //package access
System.out.println("iampackage Method");
}
protected void protectedMethod() {
System.out.println("iamprotected Method");
}
public void publicMethod() {
System.out.println("iampublic Method");
}

public static void main(String[] args) {
Alpha a = new Alpha();
a.privateMethod(); //legal
a.packageMethod(); //legal
a.protectedMethod(); //legal
a.publicMethod(); //legal

System.out.println("iamprivate: "
+ a.iamprivate); //legal
System.out.println("iampackage: "
+ a.iampackage); //legal
System.out.println("iamprotected: "
+ a.iamprotected"); //legal
System.out.println("iampublic: "
+ a.iampublic); //legal
}
}
------------------------------EOF------------------------------------------


-----------------------------DeltaOne.java---------------------------------
package One;
public class DeltaOne {
public static void main(String[] args)
{
Alpha a = new Alpha();
//a.privateMethod(); //illegal
a.packageMethod(); //legal
a.protectedMethod(); //legal
a.publicMethod(); //legal
//System.out.println("iamprivate: "
// + a.iamprivate); //illegal
System.out.println("iampackage: "
+ a.iampackage); //legal
System.out.println("iamprotected: "
+ a.iamprotected); //legal
System.out.println("iampublic: "
+ a.iampublic); //legal
}
}
----------------------------------EOF------------------------------------

If everything else fails, read the JAR tutorial at:

Thanks for the help

I created a manifest.txt file with the contents
------------------------------------------------------------------------------
Manifest-Version: 1.0
Created-By: 1.5.0_01-b08 (Sun Microsystems Inc.)
Main-Class: one.Alpha
------------------------------------------------------------------------------

The classes Alpha.class and DeltaOne.class were in the same directory
In the directory i gave the command: -

jar -cfm one.jar manifest.txt Alpha.class DeltaOne.class

But when i executed the jar file
java -jar One.jar
It gave the exception
Exception in thread "main" java.lang.NoClassDefFoundError: one/Alpha

Any help
Thanks

Main-Class: one.Alpha
------------------------------------------------------------------------------

Only Alpha has to be written i.e the manifest line should be
Main-Class: Alpha
