Enum In java

In java we use of enum is not confined to declaring set of constants , introduced in J2SE 5.0, is useful when you want a variable to hold only a predetermined set of values. Just like a class, an enum can have constructors, methods, and variables in addition to the constants.

The most interesting fact about enum is enum can be used as a stand alone application as we can define the main method in it , the following code describe the use of enum in java with main method.

enum Cars {
    THAR,XUV,SCORPIO;

    static public void main(String[] args) {
        for (Cars name : Cars.values()) 
               System.out.print(name + " ");
   }

}

In the following code the enum Cars is created with three constants THAR, XUV, SCORPIO , it have a main method to print the all constants of the enum.
