我怎么能够把清单列入一个很长的时期?
原标题:How can I index the arraylist by a long?

I have filled an arraylist<string> with 20 lacs strings. If I want to iterate like this,

for(long i=0;arrlist.size();i++{
   arrlist.get(i);  

}

但是,arrlist.get()t t supportindex as long. 此外,我不能使用自动取款机,因此,没有<条码>的自动取款机/代码>? Pleas没有问为什么我不使用激光器。

问题回答

从您的提问来看,你似乎试图挑拨每个要素。 请注意,为此目的,您可使用nic子 lo:

for(String element: arrlist) {
   // Do whatever you want with your element
}  

我想arrlist.get(int) i。 或仅可宣布<代码>i为int

<代码>ArrayList#size(>>n t Returnlongint。 无需在环形体内使用<条码>长期变量。
