+##Item 3: Enforce the singleton property with a private constructor or an enum type
+The main advantage of the public field approach is that the declarations make it clear that the class is a singleton:
+the public static field is final, so it will always contain the same object reference.
+
+###Serialization of singleton
+To make a singleton class that is implemented using either of the previous approaches serializable (Chapter 11),
+it is not sufficient merely to add imple- ments Serializable to its declaration.
+To maintain the singleton guarantee, you have to declare all instance fields transient and provide a readResolve method

+##Item 5: Avoid creating unnecessary objects
+###Immutability
+An object can always be reused if it is immutable. Take the example of extraobjectcreation package.
+String can be reused, rather than again and again using constructor.
+
+The static factory method ```Boolean.valueOf(String)``` is almost always preferable to the constructor Boolean(String).
+
+###Mutable objects can be reused too
+In the slowversion package we are again and again creating boomstart and boomend object. 
+In the fastversion, we have just create it once in static block and reusing it again and again.
+the keySet method of the Map interface returns a Set view of the
+Map object, consisting of all the keys in the map. Naively, it would seem that every
+call to keySet would have to create a new Set instance, but every call to keySet
+on a given Map object may return the same Set instance. Although the returned
+Set instance is typically mutable, all of the returned objects are functionally identical:
+when one of the returned objects changes, so do all the others because
+they’re all backed by the same Map instance. While it is harmless to create multiple
+instances of the keySet view object, it is also unnecessary.
+
+###Issue due to autoboxing
+There’s a new way to create unnecessary objects in release 1.5. It is called autoboxing.
+This program gets the right answer, but it is much slower than it should be,
+due to a one-character typographical error. The variable sum is declared as a Long
+instead of a long, which means that the program constructs about 231 unnecessary
+Long instances (roughly one for each time the long i is added to the Long sum).
+Changing the declaration of sum from Long to long reduces the runtime from 43
+seconds to 6.8 seconds on my machine. The lesson is clear: prefer primitives to
+boxed primitives, and watch out for unintentional autoboxing.
+
+###Issue with object pool
+Conversely, avoiding object creation by maintaining your own object pool is a
+bad idea unless the objects in the pool are extremely heavyweight. The classic
+example of an object that does justify an object pool is a database connection.
+

+##Item 7: Avoid finalizers
+Finalizers are unpredictable, often dangerous, and generally unnecessary.
+
+Don’t be seduced by the methods System.gc and System.runFinalization.
+They may increase the odds of finalizers getting executed, but they don’t guarantee
+it. The only methods that claim to guarantee finalization are System.runFinalizersOnExit
+and its evil twin, Runtime.runFinalizersOnExit. These
+methods are fatally flawed and have been deprecated
+
+###Examples of Terminiation methods - Terminate method pattern
+Typical examples of explicit termination methods are the close methods on
+InputStream, OutputStream, and java.sql.Connection. Another example is
+the cancel method on java.util.Timer, which performs the necessary state
+change to cause the thread associated with a Timer instance to terminate itself
+gently. Examples from java.awt include Graphics.dispose and Window.dispose.
+These methods are often overlooked, with predictably dire performance
+consequences. A related method is Image.flush, which deallocates all the
+resources associated with an Image instance but leaves it in a state where it can
+still be used, reallocating the resources if necessary.
+
+###try-finally
+Explicit termination methods are typically used in combination with the
+try-finally construct to ensure termination. Invoking the explicit termination
+method inside the finally clause ensures that it will get executed even if an
+exception is thrown while the object is being used:
+// try-finally block guarantees execution of termination method
+```
+Foo foo = new Foo(...);
+try {
+// Do what must be done with foo
+...
+} finally {
+foo.terminate(); // Explicit termination method
+}
+```
