For instance, without Java Generics the Java List, Java Set, Java Map etc. interfaces would all be working on Object instances. With Java Generics you can create List, Set or Map instances that work on specific types, e.g. a List of Strings, rather than a List of Objects, so you ...

要在java中创建一个List,我们可以使用它的两个具体子类之一:ArrayList和LinkedList。我们将使用ArrayList创建一个List,并在程序部分中使用list接口提供的测试方法。 List p = new ArrayList(); List q = new LinkedList(); List r = new Vector();
Creating a Generic ArrayList object can also be done in separate lines like this: ArrayList<String> arlist; arlist = new ArrayList(); 注意:我们不能使用原始数据类型作为类型。例如,ArrayList<int>是非法的。 Java ArrayList Initialization 在Java 中初始化数组列表有三种方法。它们如下: ...
