Java Programming with J2SE 5: Creating Classes in Java

Course details

To enable the learner to create and work with Java classes and objects

• Classes, objects, and messages in Java
• identify how encapsulation affects a Java class, and pass messages between objects.
• Creating Java classes
• identify the code required to declare a specific class and a constructor for a class.
• Creating methods
• identify the code required to declare a method and implement a variable argument list in a method for a given scenario, and declare a variable in a class based on that variable's scope.
• Creating classes and methods
• write an appropriate class and method declaration, and pass variable arguments to a method.
• Working with Java objects
• create an object, call an object's method, and assign the result of the method to an existing variable for a given scenario.
• Type safe enums
• create, iterate over, and switch on type safe enums in J2SE 5.0.
• Creating objects and enums
• create a Java enumeration and object, iterate over the enumeration's values, and call one of the object's methods.
• Declaring and importing Java packages
• create a package in a given scenario, and import classes, static methods, and variables into a source file.
• Controlling access using Java access modifiers
• identify the appropriate level of access to apply to classes, variables, methods, and constructors for a given scenario.
• Using Java packages and access modifiers
• create and import a specific Java package, import static methods and variables into a source file, and identify the access levels of the class members in that package.
