How can I use instance methods created with HashMap

Question

class Template
static HashMap customer;
a few methods created various customer
public static display() //to display a particular customer information among i've created above
             String objectName,currentObjectName;
          Customer customer;
          Scanner scan=new Scanner(System.in);
          System.out.print("Please enter the customer name");
          objectName=scan.nextLine();
          Iterator iteratorForCustomer=CustomerMap.entrySet().iterator();
          Map.Entry customerEntry=(Map.Entry)iteratorForCustomer.next();
         while(iteratorForCustomer.hasNext())
                customerEntry=(Map.Entry)iteratorForCustomer.next();
                if(objectName.equals((String)customerEntry.getValue()))
          System.out.println("Name : " +customer.getName()); //I'm trying to reference to an instance method getName() here but i can't do that .
}The problem is I've created as many as I want and later in the program I tried to redisplay a particular customer information based on the input (objectName). User type in the objectName and I tried to look for a particular customer Object in the HashMap and display only the relevant customer information. Is there any way to do it ? Thanks everyone in advance.

And then either look at a generics tutorial, or, if you're stuck on a pre-1.5 version of Java, find out about casting
