The code looks fine for the most part. A few things that I would have done differently are: Since you have a constructor that takes in all.

NET initiative. What is JavaScript? When new technologies start, they sometimes acquire names that will be confusing in the future. That's the case with JavaScript. JavaScript is not 'Java'. JavaScript is a simple programming language that was developed by Netscape that writes commands to your browser when the HTML page is loaded.

Note: you can have compatibility issues with Java Script, especially in newer versions of Browsers. What is Java? Java is a simple, distributed object oriented programming language which provides the security, High performance, robustness. Java is a portable and Architectural neutral language which can be Interpreted. Java is multithreaded and Dynamic language.

Java applications are typically compiled to bytecode class file that can run on any Java Virtual machine JVM regardless of computer architecture. Goals in creation of Java There were five primary goals in the creation of the Java language 1. It should be "simple, object oriented". It should be "robust and secure". It should be "architecture neutral and portable".

PHONE BOOK APPLICATION

It should execute with "high performance". It should be "interpreted, threaded, and dynamic". You express the program in source files written in the Java programming language, compile the source to Java class files, and run the class files on a Java virtual machine.

The Java Virtual Machine At the heart of Java's network-orientation is the Java virtual machine, which supports all three prongs of Java's network-oriented architecture: platform independence, security, and network-mobility.

A Java virtual machine's main job is to load class files and execute the bytecodes they contain. As you can see in Figure , the Java virtual machine contains a class loader, which loads class files from both the program and the Java API. Only those class files from the Java API that are actually needed by a running program are loaded into the virtual machine.

The bytecodes are executed in an execution engine. Coding standard Java suggests set of coding standard to follow while writing java program.

Coding standard helps author as well as others to better understand program.

It reduce amount of debugging time considerably. Basically coding standard suggests how to name class, methods variables of different scope, package etc. Writing a Java program In the Java programming language, all source code is first written in plain text files ending with the. Address Book creates a database called DefaultAddressBook in a subdirectory of the user's home directory, and it does so without asking the user for any additional information.

Because our application will use the DefaultAddressBook database, we should first create this database. Assuming that the application has already set the derby.

Creating the database doesn't actually create any application tables. However, you should now be able to find a new subdirectory named. After it has created the database, the application creates the tables. Java DB generates this value for each new record that it adds to the database.

The ID field is the primary key for each address record. All remaining address record fields contain varchar elements of various lengths. The varchar type is equivalent to a UTF Java char code unit. The dbConnection is the same as the one shown in the previous code.

We simply pass it into createTables, create a new Statement, and call the execute method to run the SQL code on the newly formed database. Although you can browse this subdirectory, avoid modifying any files.

If you edit or delete any of these database files directly, you can destroy the integrity of your database. Using the Database Once the database and its tables have been created, your application can create new connections and statements to add, edit, delete, or retrieve records.

Figure 5 shows the available options: New.

Components

Create a new address record. Delete the displayed address record.

Edit the displayed address record. Save the new or edited address record that is displayed. Cancel any edits or any attempt to create a new record.

Figure 5: Address Book has several options for interacting with records. The main window of the application is AddressFrame, which acts as a controller and as a view at the same time.

It registers itself with the AddressActionPanel to receive notification when a user clicks anywhere on the action bar. The New command clears the address entry panel and enables the user to edit all fields. The Delete command attempts to delete the currently selected address record.

AddressFrame retrieves the currently selected Address identifier from the AddressPanel and uses AddressDao to delete the record. After deleting the record from the database, the application must delete the ListEntry from the AddressListPanel too. The AddressDao creates a PreparedStatement when it first connects to the database.

For example, you can change the name, city, or phone number of a saved record.

The Save command retrieves either the newly created or edited Address from the AddressPanel and attempts to either update the existing record or create a new record.

If the user has been editing a record, Save will update that record with the new information. If the user has created a new record, Save will insert a new record in the database.

New records have not yet been saved. At this point, their ID field is still set to the default -1 value.After selecting the desired one, he will be able to see the contact details associated with that name.

The dbConnection is the same as the one shown in the previous code. The following manifest does both, and we can include it when building AddressBook. These buttons should allow the user to perform the corresponding actions on the individual name and address, the number or donations, and the donation amount. Use a constructor to initialize the individual information, and a method within that class to calculate the yearly donation total.

If either the donation amount or the number of donations is not a positive value, the application should prompt the user to enter a positive amount.

The ANT build file, build. Of course, when you create a new record, the application must also update the AddressListPanel.

Java is multithreaded and Dynamic language. The application can control where the database exists, what tables exist, and how permissions are handled.
