(1)Collection接口:是存放一组单值的最大接口。 所谓的单值是指集合中的每个元素都是一个对象。一般很少直接使用此接口直接操作。 (2)List接口: 是Collection接口的子接口 ,也是最常用的接口。此接口对Collection接口进行了 大量的扩充,里面的内容是允许重复允许为NULL的并且有序(插入)。 (3)Set接口: 是Collection...
Java provides a special syntax of for loop (also called for-each loop) to process arrays and iterable collections. Any iterable collection has to implement an iterator() method that returns an Iterator object. And the class implements Iterator has to implement two methods: hasNext() (returns ...
Stack class is a part of the Java Collections Framework. It extends the Vector class and implements List, Collection, Iterable, Serializable, and Cloneable interfaces. It is a part of java.util package. Just like we create our own stack, we have predefined methods in the Stack class to push...
