&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;== Lazy Initialization ==&lt;br /&gt;
ExplicitInitialization의 모든 장점은 단점으로, 단점은 장점으로 된다. 당연하다.(--;)&lt;br /&gt;
LazyInitialization의 하나의 변수당 두개의 메소드로 나눠서 초기화를 한다. 하나는 변수가 LazyInitialization되는 것을 감추어 주는 getter이고, 다른 하나는 변수에다 디폴트값으로 할당을 해줄 DefaultValueMethod이다. 이 방법은 유연성이 증대된다. 당신이 서브클래스를 만든다면, DefaultValueMethod를 오버라이딩함으로써, 기능을 바꿀 수 있다. 전장에서도 언급했듯이 성능도 증대시킬 수 있다.&lt;br /&gt;
----&lt;br /&gt;
변수마다 getter를 만들자. 필요하다면 DefaultValueMethod를 써서 초기화를 하자.&lt;br /&gt;
----&lt;br /&gt;
앞에서 살펴본 타이머 예제로 해보자.&lt;br /&gt;
 Class Timer&lt;br /&gt;
 {&lt;br /&gt;
 /* ... */&lt;br /&gt;
 	int getCount()&lt;br /&gt;
 	{	&lt;br /&gt;
 		if(!count)	// --; 어쩔수 없다. 그냥 옮긴거다.&lt;br /&gt;
 			count = defaultCount();&lt;br /&gt;
 		return count;&lt;br /&gt;
 	}&lt;br /&gt;
 	int defaultCount()&lt;br /&gt;
 	{	&lt;br /&gt;
 		return 0;	// 상수로 해결가능할듯&lt;br /&gt;
 	}&lt;br /&gt;
 	int getPeriod()&lt;br /&gt;
 	{&lt;br /&gt;
 		if(!period)&lt;br /&gt;
 			period = defaultPeriod();&lt;br /&gt;
 		return period;&lt;br /&gt;
 	}&lt;br /&gt;
 	int defaultPeriod()&lt;br /&gt;
 	{&lt;br /&gt;
 		return 1000;	// 상수로 해결가능할듯&lt;br /&gt;
 	}&lt;br /&gt;
 };&lt;br /&gt;
----&lt;br /&gt;
별로 안쓸듯하지만... 켄트벡 왈 : 일단은 ExplicitInitialzation으로 출발을 하고, 상속될 거 같으면 LazyInitialization을 사용한다.&lt;br /&gt;
