通过ArrayList获得枚举类型

1. ArrayList<InputStream> al = new ArrayList<InputStream>();
   
2. for(int i =1;i<5;i++)
   
3. {
   
4.         al.add(new FileInputStream(i+".part"));
   
5. }
   
6. final Iterator<InputStream> it = al.iterator();
   
7. Enumeration<InputStream> en= new Enumeration<InputStream>(){
   
8. public boolean hasMoreElements() {
   
9. return it.hasNext();
   
10. }
    
11. public InputStream nextElement() {
    
12. return it.next();
    
13. }
    
14. };
