list集合遍历

List list=new ArrayList();
list.add(“111”);
list.add(“222”);
list.add(“333”);

for遍历
for(int i=0;i<list.size();i++){
System.out.println(list.get(i));
}
增强for遍历
for(Sting i:list){
System.out.println(i);
}
迭代器遍历
Iterator it =list.iterator();
while(it.hasNext()){
System.out.println(it.next);
}
