I have updatedthe code and changedit to
  more robust implementation.
  public class SimpleSingleton private staticSimpleSingletonsingleInstance = new SimpleSingleton(); //Markingdefaultconstructor private //to avoid direct instantiation.privateSimpleSingleton() //Get instance for class SimpleSingletonpublicstatic SimpleSingleton getInstance() returnsingleInstance;
  public class SimpleSingleton private staticSimpleSingletonsingleInstance = new SimpleSingleton();
  //Marking default constructor private//to avoiddirectinstantiation.private SimpleSingleton()
  //Get instance for class SimpleSingletonpublicstaticSimpleSingleton getInstance()
  return singleInstance;One more implementation of Singletonclass.Thanks to Ralph and Lukasz Zielinski
  for pointing this out.
  public enum SimpleSingleton INSTANCE; publicvoiddoSomething()//Call the method fromSingleton:SimpleSingleton.INSTANCE.doSomething();
  public enum SimpleSingleton INSTANCE;public voiddoSomething()
  //Call the methodfromSingleton:SimpleSingleton.INSTANCE.doSomething();
