Java中如何对LinkedList进行遍历呢？

for循环(随机访问)遍历

int size = list.size();  
for (int i=0; i<size; i++) {  
    list.get(i);          
}  

for--each循环遍历

for (Integer integ:list){
 ;
}

迭代器iterator遍历

for(Iterator iter = list.iterator(); iter.hasNext();)  
    iter.next();  

用pollFirst()遍历

while(list.pollFirst() != null)  
    ;  

用pollLast()遍历

while(list.pollLast() != null)  
    ;  

用removeFirst()遍历

try {  
    while(list.removeFirst() != null)  
        ;  
} catch (NoSuchElementException e) {  
}  

用removeLast()遍历

try {  
    while(list.removeLast() != null)  
        ;  
} catch (NoSuchElementException e) {  
}
