有如下数组:

String str [] ={"a", "b", "c", "d", "e"};

1.for循环遍历

for(int i = 0; i < str.length; i++){

  System.out.println(str[i]);

}

2.foreach遍历

for(String x : str){
  System.out.println(x);
}

3.迭代遍历

List list = Arrays.asList(str);
Iterator iterator = list.iterator();
while(iterator.hasNext()){
  System.out.println(iterator.next());
}
