//File Name:MyPreviousClass.java
//reciding at path c:\mydir1\mydir2\MyPreviousClass.java
package mydir2;
public class MyPreviousClass{
public void aMethod(){
}
}
//File Name:MyCurrentClass.java
//reciding at path c:\mydir1\mydir2\MyCurrentClass.java
package mydir2;
import mydir2.MyPreviousClass;
public class MyCurrentClass{
public void aNewMethod(){
MyPreviousClass mpc=new MyPreviousClass();
}
}
I have compiled the class MyPreviousClass.java with the command
c:\mydir1\mydir2> javac MyPreviousClass.java
My Problem:
Now how and from where to compile the class MyCurrentClass.java ?
Actually I am not ok with the package funda...pls explain the reason for ur answer..and a bit about the package funda so that i can grasp the subject.
Thanks

Hi,
U can compile the other class also, from the same directory, since the second class is also placed in the same package.
Since both the classes are in the same package, the statement,

is not necessary.
Moreover, you need not explicitly create physical folder and then compile the classes. Try this,
  • Create both the classes in the folder c:\mydir1
  • go to c:\mydir1 and type, c:\mydir1>javac -d . MyPreviousClass.java
  • c:\mydir1>javac -d . CurrentClass.java

  • The -d option followed by the location( "." indicates the current folder, u can also say, javac -d c:\temp filename.java) will automatically create the required folders, specified as the name of the package(here, mydir2) and place the .class file there.
    U can execute the files as
    c:\mydir1> java mydir2.CurrentClass
    Hope this helps u...
    Regards,
    Uma......
