packages and compilation problem

[abhishek kunal]

my project have a package and i have two java files

1. abstractcheck.java

package pkcheck;
public class abstractcheck extends firstabstract
{
public void another()
{
}
public void mymethod1()
{
System.out.println("hello javaranch");
}
public static void main(String args[])
{
utility ui = new utility();
System.out.println(ui.data);
}
}

and the 2. myabstract2.java

package pkcheck;
abstract class firstabstract
{
public abstract void mymethod1();
public abstract void another();
}
public abstract class myabstract2
{
public abstract void mymethod1();
}
class utility
{
int data = 45;
} 

now as utility class (which is in myabstract2.java,non-public )is in package pkcheck, so that should be accessible in abstractcheck.java, bevause both are in same package, however this runs well in netbeans, but when i run it from command prompt, then it says cannot find symbol, utility and other non-public classes. what may be the problem..please help!!

i tried even classpath flag also...

Try compiling all the classes together with javac -d . *.java or javac pkcheck/*.java
Otherwise compile the dependency classes before you compile the client classes.

thank you very much!! ..it works,now i have another problem, would you suggest me??

now i created another package in pkcheck package and in that package i have one java file,utility2.java , package name is another, now i want to compile all the classes directly in pkcheck package and in all of it's subpackages , here another...

obviously i will run javac from the parent directory of pkcheck and i want classes to be stored in same directory(package) structure in some other directory..so i thought...this command should work...

javac pkcheck/*/*.java , but that didn't work anyway....so please tell the correct command for that..i used other combination's as well....

Too busy for a lengthy answer at the moment. Sorry.
Please do a search for "package" and "compile", particularly my posts. I write about that sort of thing quite frequently. You may need to move onto "ant" if you have that sort of package structure.

Have look at this post from last week and the older links I posted there. That should help you; as I said this is quite a frequent question.
