5. 使用迭代器进行迭代操作 迭代器(Iterator)是Java集合框架中的一个重要概念,它提供了一种统一的方式来遍历集合中的元素,并且可以在迭代过程中进行元素的增删改查操作。以下是使用迭代器实现迭代操作的示例代码: List<String>list=Arrays.asList("apple","banana","orange");Iterator<String>iterator=list.iterator...
//1.values Stream stream = Stream.of("a","b","c"); //2. Arrays String[] arrays = String[]{"a","b","c"}; stream = Stream.of(arrays); stream = Arrays.stream(arrays); //3. Collections List<String> list = Arrays.asList(arrays); stream = list.stream(); 1. 2. 3. 4. ...

Note that you need to return string. Which means any poperty with datatype other than String needs to be converted to string before returning. Also, if you’re using an IDE, you don’t need to do all of this manually. For example: in Eclipse, you can generate a toString method by op...
