Question

this is partly homework I’ve been given some code to use and I am trying to figure out one part of it…

   public PhoneAccount[] getAllAccounts() {
      return tm.values().toArray(new PhoneAccount[tm.size()]);
   }

I am trying to find out how to read this in my main method, I’ve created the instance of the class this is. Which I named “am”

What exactly do I need to do to make it list the contents of the array?

am.getAllAccounts() 

is what it is, just not sure how do I make it print its contents?

Answer 1

Suppose you have totalBill property in PhoneAccount , then you can print it using the below code.

PhoneAccount[] phoneaccounts = am.getAllAccounts() ;
for( PhoneAccount phoneaccount  : phoneaccounts)
{
 System.out.println(phoneaccount.getTotalBill());
// fetch all the  other properties from phoneaccoun similarly.
}
