Array String []a = new String[10] ; a[0] = "test" ;
String []a = new String[]{"test","test01","test02"} ;
String []a = {"test","test01","test02"} ;
========================数组声明的三组方式=========================
ArrayList ArrayList staff = new ArrayList();
note:数组和数组列表最大的区别是,数组的size是确定的,而数组列表的size是
动态的；
=================================================
Iterator 迭代器的使用:
ArrayList<String> list = new ArrayList<String>();
list.add("aa");
list.add("bb");
list.add("cc");
Iterator<String> iter = list.iterator();
while(iter.hasNext()){
String str= iter.next();
System.out.println(str);
}
java中array，arraylist，iterator；
