Java迭代器遍历list的方法及代码分析

import java.util.ArrayList;
import java.util.Iterator;
public class Demo {
public static void main(String[] args) {
ArrayList aList = new ArrayList();
aList.add("Apple");
aList.add("ManGo");
aList.add("Guava");
aList.add("Orange");
aList.add("Peach");
System.out.println("The ArrayList elements are: ");
for (Iterator iter = aList.iterator(); iter.hasNext();) {
System.out.println(iter.next());
}
}
}

The ArrayList elements are:
Apple
Mango
Guava
Orange
Peach

ArrayList aList = new ArrayList();
aList.add("Apple");
aList.add("Mango");
aList.add("Guava");
aList.add("Orange");
aList.add("Peach");
System.out.println("The ArrayList elements are: ");
for (Iterator iter = aList.iterator(); iter.hasNext();) {
System.out.println(iter.next());
}
