Java Enum notes Date and Time formatting

Java Enum is also a class.

 

Public Enum action {
Turn_left,
Turn_right,
Shoot;
Public String getdescription (){

Switch (this. ordinal ()){
Case 0: Return "Left ";
Case 1: Return "right ";
Case 2: Return "shoot ";
Default: return NULL;
}
}
}

 

 

E. G.2:

 

Code

Public Enum actionabstract {
Turn_left
{
Public String getdesc () {return "Left ";}
},
Turn_right {
Public String getdesc () {return "right ";}
},
Shoot {
Public String getdesc () {return "shoot ";}
}; // End;

Public abstract string getdesc ();
}

 

 

PS:

 

For (Action Act: Action. Values ()){
System. Out. printf ("% S % N", act. ordinal (), Act );
}

// Date and Time Format expression:

System. Out. println (
String. Format ("% 1 $ ty-% 1 $ TM-% 1 $ TD % 1 $ TH: % 1 $ TM: % 1 $ ts", new date ())
);
System. out. printf ("% 1 $ ty-% 1 $ TM-% 1 $ TD % 1 $ TH: % 1 $ TM: % 1 $ ts", new date ());
