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();
