九、Java集合 、Collection子接口二:Set 六、Map接口 七、Collections工具类一、Java集合框架概述1.1数组的弊端集合、数组都是对多个数据进行存储操作的结构,简称Java容器数组在内存存储方面的特点:数组初始化以后,长度就确定了数组声明的类型,就决定了进行元素初始化时的类型数组在存储数据方面的弊端:数组初始化以后,长度...
Collection<String> coll3 = new ArrayList<String>(); coll3.add("abc"); coll3.add("ddd"); coll3.add("eee"); 分析,集合对象中的元素的类型是变化的,方法的形参的那么泛型类型就只能定义为Object类型. import java.util.ArrayList; import java.util.Collection; import java.util.HashSet; import java...
It's rather hard to do a true generic tree implementation in Java that really separated the tree operations and properties from the underlying implementations, i.e. swap in a RedBlackTreeNode and override a couple of method to get a RedBlackTree implementation while retaining all the generic o...
test.add(new AnyAbstractGroupSubGroup()); //I would guess that a method call such as this at runtime test = new HashSet<SubGroupA>() //would mean that only objects of subgroupA can be added to the collection, but then //what is the point in using the wildcard in the first place?
8.22.4. You cannot add non-related class to generic collection instance 8.22.5. When retrieving a member of a generic vector, you can reference without casting. 8.22.6. Iterators may be generic. 8.22.7. Sets can be generic. 8.22.8. Using a generic Iterator to compute the average length...

Inserts the elements of a collection into the List<T> at the specified index. LastIndexOf(T, Int32, Int32) Searches for the specified object and returns the zero-based index of the last occurrence within the range of elements in the List<T> that contains the specified number of elements...
