Java single example, enumeration implementation method

Publicenum singletonenum

{

    instance01,instance02;

    private String name;

    Publicstring getName ()

    {

       returnname;

    }

     Publicvoid SetName (String name)

    {

       this.name = name;

    }

 }


Test public

class test
{public
    static void Main (string[] args)
    {
        Singletonenum instance01= SINGLETONENUM.INSTANCE01;
        Instance01.setname ("Terje");
        System.out.println (Instance01.getname ());
       
        Singletonenum instance02=singletonenum.instance01;
        System.out.println (Instance02.getname ());
       
        Singletonenum Instance03=singletonenum.instance02;
        Instance03.setname ("Liu");
        System.out.println (Instance03.getname ());
       
        Singletonenum Instance04=singletonenum.instance02;
        Instance04.setname ("Liu");
        System.out.println (Instance04.getname ());

    }

Output:

Terje
