Required Tutorials
- The Object Oriented Paradigm; Classes and Objects
- Notions About the Java Language
- Writing and Executing a Java Program
- Java Syntax; A Program's Lexical Structure
- Java Coding Conventions
Requirements
- Create a Java application project whose name contains your name and group using the format group_surname_name (use a single name and a single surname). Student John Codebreaker from 421G will create a project named 421G_Codebreaker_John .
- Add to your project a class Message (that may be used some time in the future as a data carrier between a chat client and all the other clients connected to a server). This class needs to:
- Store the name of the sender and a message content.
- Be immutable (once an object of this type is created, its contents can't be changed).
- Allow reading of the sender and content information from Message objects in a way specific to chat programs: "sender: contents". This must be done using only one method call that returns the formatted string, ready to be displayed by any print method. Try first with a method of your own. Then, add another method, that does exactly the same thing but whose declaration is public String toString().
- Write another class called Main (the default class created if you created a project within NetBeans), which should contain only the main method, that instantiates at least three objects of type Message and then displays their formatted string on the screen.
Notes:
- Each class and class member must have one of the two access modifiers public or private.
- The names of the classes must be identical to the ones specified above.
- Follow the coding rules stated in Java Coding Conventions.
Submitting:
- The assignment is submitted attaching the Java source code files to an e-mail sent to arhitectura_procesoarelor@yahoo.com
- The subject of the e-mail will be: OOP_1
- The body of the e-mail contains only the name of your project, exactly as it appears in the package declarations.
- Attention Any deviation from these instructions may lead to the loss of the entire amount of points.
