How will you draw an efficient singleton pattern in java?

Question

I want to know is there any optimized way to draw a singleton pattern in Java?

Answer 1

The very concise way of writing singleton in Java is using enum-type. This approach is very handy when it comes to functional equivalency in the public field. 

public enum Sandeep { 

INSTANCE; 

private final String[] favoriteBeach = 

{ "Goa", "Kovalam" }; 

public void printFavorites() { 

System.out.println(Arrays.toString(favoriteBeach)); 

} 

}
