Package & Compilation Problem

[Moguluri Ravi Kiran]

Hello
this is Kiran and i getting compilation error on packages.

MyDir
| - Class1.java
| - Class2.java
| - p1(package dir)
----------> | - Class1.class (it is generated successfully)
| - Class2.class (error while compiling this)

& My Classes are

package p1;

public class Class1 {
  static {
    System.out.println("Package1 - Class1");
  }
}



import p1.*;

class Class2 {
  public static void main(String a[]) {
    new Class1();
  }
} 

output
******
D:\javap\MyDir>javac Class2.java
Class2.java:7: cannot access Class1
bad class file: .\Class1.java       
file does not contain class Class1
Please remove or make sure it appears in the correct subdirectory of the classpa
th.
      new Class1();
          ^
1 error

Now when ever i remove the "Class1.java" from the MyDir ---- there is no error. & successful compilation,running.
when ever i place the "Class1.java" in the MyDir ---- error appears......... what is the reason for this ?

In short, when you use "import p1.*", the compiler looks for the "Class1" and find it the current dir. In order to explicitly tell the compiler to look for the dir "p1" either you have to use the full reference, like "p1.Class1" OR mention it on CP. But when you delete the java file then it looks for the "p1" dir.

Moguluri, the problem lies in the way your source files are located. When I put Class1.java inside folder p1, then run "javac Class2.java", I get no errors. If I move Class1.java to the root folder and remove folder p1 I also get an error. Try always using the package structure for your source files as well.
