Running package using -classpath switch

Question

Hi,
I have made a program and specified the package key word at the top of prog and then storing it in the package directory. I have created the class file but when I try to run the program from D:\> , I am getting errors.
package MyPack;
class Balance{
   String  name;
   double  bal;
   Balance  (String n, double b) {
      name=n;
      bal=b;
  void  show ( ) {
    if(bal < 0)
       System.out.println("--> ");
    System.out.println(name + ": $" + bal);
class AccountBalance{
   public  static  void  main (String  args[ ]) {
   Balance  current [ ] = new Balance[3];
   current[0]=new Balance("K. J. Fielding", 123.23);
   current[1]=new Balance("Will Tell", 157.02);
   current[2]=new Balance("Tom jackson",-12.33);
  for (int i=0; i< 3; i++) current.show ( );
class is stored in the following directory:
D:\javaprogs\misc\Packages\MyPack
D:\>java -classpath D:\javaprogs\misc\Packages AccountBalance
Exception in thread "main" java.lang.NoClassDefFoundError: AccountBalance
D:\>java -classpath D:\javaprogs\misc\Packages\ AccountBalance
Exception in thread "main" java.lang.NoClassDefFoundError: AccountBalance
D:\>
What's the prob with the statements I have written for running the program?

Answer 1

java -classpath D:\javaprogs\misc\Packages MyPack.AccountBalance Also, it's customary in Java to name packages in all lowercase. So MyPack would be mypack.
