JAVA Package Query

[Tulika Rai]

I have created 2 packages pkg1 and pkg2, my directory structure is :

c:\ABC\pkg1
c:\ABC\pkg2

I have created a file TestProtectedSuper.java in pkg1 and TestProtectedSub.java in pkg2

when I am individually compiling and running pkg1.TestProtectedSuper it is running fine, but when I am trying to use this file in pkg2.TestProtectedSub.java,
getting compilation error :

package pkg1 does not exist

cannot fine symbol for class TestProtectedSuper

code for TestProtectedSuper.java :

package pkg1;

public class TestProtectedSuper
{
protected int age;
public TestProtectedSuper(int ag)
{
age=ag;
}

/*public static void main(String args[])
{
System.out.println("TestProtectedSuper");
}*/

}

Code for TestProtectedSub.java is :

package pkg2;
import pkg1.TestProtectedSuper;
public class TestProtectedSub
{
public static void main(String[] args)
{
System.out.println("Testing Protected Variable in different package");

TestProtectedSuper obj1=new TestProtectedSuper(10);
System.out.println("age is : " + obj1.age);
}
}

Can anyone help me in solving my problem.....

because age variable has protected access modifier and hence can not be accessed by any class but subclass outside the package.

    package pkg2; 
import pkg1.TestProtectedSuper; 
public class TestProtectedSub extends TestProtectedSuper
{ 


public TestProtectedSub(int ag) {
		super(ag);
		// TODO Auto-generated constructor stub
	}

public void test(){
	System.out.println(age);
}

public static void main(String[] args) 
{ 
System.out.println("Testing Protected Variable in different package"); 

TestProtectedSuper obj1=new TestProtectedSuper(10); 

} 
}

because age variable has protected access modifier and hence can not be accessed by any class but subclass outside the package.

The above should have raised an error in this line, and which is obviously going to occur

System.out.println("age is : " + obj1.age);
   

But the error which occurred first is

package pkg1 does not exist

So it looks like a classpath issue.

It might simply be an error about which directory the command line uses as current. Try running it from the directory one level above pkg1, ie ABC.
