Spring 5 Design Patterns

Sample implementation of the Prototype design pattern

I am going to create an abstract Account class and concrete classes extending the Account class. An AccountCache class is defined as a next step, which stores account objects in a HashMap and returns their clone when requested. Create an abstract class implementing the Clonable interface.

    package com.packt.patterninspring.chapter2.prototype.pattern;    public abstract class Account implements Cloneable{      abstract public void accountType();      public Object clone() {        Object clone = null;        try {          clone = super.clone();        }        catch (CloneNotSupportedException e) {          e.printStackTrace();        }        return clone;      }    }

Now let's create concrete classes extending the preceding class:

Here's the CurrentAccount.java
