简化集合的创建
List<Person> personList= Lists.newLinkedList();
Set<Person> personSet= Sets.newHashSet();
Map<String,Person> personMap= Maps.newHashMap();
Integer[] intArrays= ObjectArrays.newArray(Integer.class,10);
简化集合的初始化
Set<String> set = Sets.newHashSet("one","two","three");
List<String> list = Lists.newArrayList("one","two","three");
Map<String, String> map = ImmutableMap.of("ON","TRUE","OFF","FALSE");
List<Person> personList2= Lists.newArrayList(new Person(1, "Ryu"), new Person(2, "Ken"));
Set<Person> personSet2= Sets.newHashSet(new Person(1, "Ryu"), new Person(2, "Ken"));
Map<String,Person> personMap2= ImmutableMap.of("p1", new Person(1, "Ryu"), "p2", new Person(2, "Ken"));
