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(); |
