Comments in Java

Java supports single-line and multi-line comments very similar to c and c++. All characters available inside any comment are ignored by Java compiler.

public class MyFirstJavaProgram{

   /* This is my first java program.

    * This will print 'Hello World' as the output

    * This is an example of multi-line comments.

    */

    public static void main(String []args){

       // This is an example of single line comment

       /* This is also an example of single line comment. */

       System.out.println("Hello World");

    }

}

Inheritance,Interfaces and Packages

Single and Multiple Inheritance

Java’s form of inheritance, as you learned in the previous sections, is called single inheritance.

Single inheritance means that each Java class can have only one superclass (although any given

superclass can have multiple subclasses).

In other object-oriented programming languages, such as C++ and Smalltalk, classes can have more than one superclass, and they inherit combined variables and methods from all those classes. This is called multiple inheritance. Multiple inheritance can provide enormous power

in terms of being able to create classes that factor just about all imaginable behavior, but it can

also significantly complicate class definitions and the code to produce them. Java makes

inheritance simpler by being only singly inherited.

Interfaces and Packages

Java has two remaining concepts to discuss here: packages and interfaces. Both are advanced

topics for implementing and designing groups of classes and class behavior.

Recall that Java classes have only a single superclass, and they inherit variables and methods from that superclass and all its superclasses. Although single inheritance makes the relationship

between classes and the functionality those classes implement easy to understand and to design,

it can also be somewhat restricting- in particular, when you have similar behavior that needs

to be duplicated across different “branches” of the class hierarchy. Java solves this problem of

shared behavior by using the concept of interfaces.

An interface is a collection of method names, without actual definitions, that indicate that

a class has a set of behaviors in addition to the behaviors the class gets from its superclasses.

Although a single Java class can have only one superclass (due to single inheritance), that class

can also implement any number of interfaces. By implementing an interface, a class provides

method implementations (definitions) for the method names defined by the interface. If two

very disparate classes implement the same interface, they can both respond to the same method

calls (as defined by that interface), although what each class actually does in response to those

method calls may be very different.

The final new Java concept for today is that of packages.

Packages in Java are a way of grouping together related classes and interfaces. Packages

enable modular groups of classes to be available only if they are needed and eliminate

potential conflicts between class names in different groups of classes.

The class libraries in the Java Developer’s Kit are contained in a package called java.

The classes in the java package are guaranteed to be available in any Java implementation,

and are the only classes guaranteed to be available across different implementations.

The java package itself contains other packages for classes that define the

language itself, the input and output classes, some basic networking, and the window

toolkit functions. Classes in other packages (for example, classes in the sun or netscape

packages) may be available only in specific implementations.

By default, your Java classes have access to only the classes in java.lang (the base

language package inside the java package). To use classes from any other package, you

have to either refer to them explicitly by package name or import them in your source

file.
