Object-Oriented Design with UML and Java The declaration statement: public class Bank{ // … // —– Relations ——— private java.util.ArrayList theAccounts; // of Account } // class: Bank in the class Bank declares a suitable ArrayList collection, theAccounts. The name for […]

Chapter 3: Implementing Objects with Java bk : Bank getBalance getTotalAssets ac2 : Account ac1 : Account getBalance Figure 3.12 Realizing the use-case Obtain the total assets of the bank Bank Operations +Bank +openAccount +creditAccount +debitAccount +getAccountBalance […]

Object-Oriented Design with UML and Java open a new account and, presumably, is given the account details. The Bank object then creates a new Account object suitably initialized. At that point we have the arrangement as shown in the second part of the figure in which two objects now exist […]

Chapter 3: Implementing Objects with Java The Create a bank object use-case is similar to that for creating a single Account object as presented in figure 3.2. The use-case Open a new account is more elaborate than that shown in chapter 2. Now we must achieve […]

Object-Oriented Design with UML and Java concepts involved by making extensive use of UML analysis diagrams. Having done so we complete our discussions by considering their implementation with detailed Java code. Further, we see this next phase as a new iteration building on our previous work. If the Account […]

Chapter 3: Implementing Objects with Java Program 3.1 The Application class (model Prog3_1.uml) public class Application{ public void run(){ // // Use-case: Open new account // Account ac = new Account( ABC123 , 1200); // // Use-case: Credit account // ac.credit(200); […]

Object-Oriented Design with UML and Java the Java code: public class Main{ // —– Operations ———public static void main(String[ ] args) { Application app = new Application(); app.run(); } // method: main } // class: Main held in the file Main.java. Figure […]

Chapter 3: Implementing Objects with Java in terms of the parameterized constructor. This is common practice when using Java and ensures consistency when developing overloaded constructors. public class Account { // —– Operations ——— // parameterized constructor public Account(String aNumber, int anInitialBalance) { […]

Object-Oriented Design with UML and Java present, must appear before all others (excepting a package statement, see chapter 4). Here we import the declaration for the classes from the textio package, thereby giving access to the classes by which we can undertake simple input and output. The class ConsoleIO that […]
