14 Java Set遍历的2种方法

Java Set遍历的2种方法

1. Iterator迭代遍历

Set<String> set = new HashSet<String>();  
Iterator<String> it = set.iterator();  
while (it.hasNext()) {  
  String str = it.next();  
  System.out.println(str);  
}
2. for循环遍历
for (String str : set) {  
      System.out.println(str);  
}
推荐用for循环进行Set的遍历。
