Java8创建Stream的几种方法

//Stream.of(T... values) 参数为一组数组
String[] strings = { "java", "js", "angular", "react", "vue" };
Stream stream1 = Stream.of(strings);
Stream stream2= Stream.of("java", "js", "angular", "react", "vue");

//Stream.empty() 无参数
Stream stream = Stream.empty();
System.out.println(stream.count());//0


//Stream.generate(Supplier s) 参数为Supplier函数接口，利用lambda表达式实现该接口，没有任何输入，返回T
Stream stream = Stream.generate(() -> "java");
stream .forEach(e -> System.out.println(e));//java
