How do I run a Java class in a package?

Question

I have two java classes as follows

App1 without a package:

class App1 {
    public static void main(String[] args) {
        System.out.         


        

Answer 1

You have to put -d directory Options..because

Set the destination directory for class files. If a class is part of a package, javac puts the class file in a subdirectory reflecting the package name, creating directories as needed. For example, if you specify -d c:\myclasses and the class is called com.mypackage.MyClass, then the class file is called c:\myclasses\com\mypackage\MyClass.class.
