Hi,
 I am creating a package pkg with a class eg1.
I am trying to use this package in class eg11.
eg1 gets compiled; but,I get the following errors while compiling eg11.java
What could the problem be? Both the files are in folder 'pkg'.

pkg/eg11.java:1: package pkg does not exist
import pkg.eg1;
           ^
pkg/eg11.java:5: cannot resolve symbol
symbol  : class eg1
location: class eg11
       eg1 myobj1 = new eg1();
       ^
pkg/eg11.java:5: cannot resolve symbol
symbol  : class eg1
location: class eg11
       eg1 myobj1 = new eg1();
                        ^

/***/
contents of eg1.java
/***/

package pkg;
 public class eg1 {

    public void show() {
       System.out.println("Testing packages");
    }
    public void oddeven(int i) {
       if((i%2)==0)
          System.out.println ("The number: "+i  +"is even");
      else
          System.out.println ("The number: "+i  +"is odd");
     }
 }

/***/
contents of eg11.java
/***/

import pkg.eg1;

 public class eg11 {
   public static void main(String args[]) {
       eg1 myobj1 = new eg1();
       myobj1.show();
       myobj1.oddeven(286);
     }
 }

Are the java files located in a folder named pkg? (they should be)

You don't need to import the class pkg.eg1 since both classes are in the same package.

And the folder should be in the directory where eg11 is, for example:
c:\test\eg11.class
and
c:\test\pkg\eg1.class

If you compiling your java file in the command prompt you have to specify the classpath to your folder containing pkg folder so that the dependent classes can be found by the compiler.

Make sure that your class-path is set to the parent folder of pkg. For example, if you have C:\TEST\MYCLASSES\pkg\eg1.class

- then the classpath should haveC:\TEST\MYCLASSES

set classpath=%classpath%;C:\TEST\MYCLASSES;.

Note - if you have the source-file eg1.java in the C:\TEST\MYCLASSES folder and compile it from there, it will make a pkg folder and the eg1.class file will be written there automatically. The class-path should be till C:\TEST\MYCLASSES. The eg11.java file should also be in C:\TEST\MYCLASSES.

Hi reachvikash,

try to compile your class from its directory, for example :
  cd c:\test\pkg\
  javac -classpath c:\test;. eg1.java
