Singleton lazy vs eager instantiation

Question

If a singleton is implemented as follows,

class Singleton {
    private static Singleton instance = new Singleton();

    public static Singleton getInstance         


        

Answer 1

You may call any other static methods or static member variable too to load the singleton instance.

class Logger {     
   private static Logger instance = new Logger(); 
   public static String LOG_LINE_SEPERATOR =  
      System.getProperty("line.separator");
   public static Logger getInstance() {  
          return instance;     
   } 

   public static String logPattern() {
       return null;
   }
} 

...

Logger.LOG_LINE_SEPERATOR; // load Logger instance or
Logger.logPattern(); // load Logger instance
