在java中的ArrayList转换到数组 [英] Converting ArrayList to Array in java

问题描述

我有像ABCD＃XYZ和MNOP＃QRS的价值观的ArrayList。我想把它转换成一个数组，然后用＃作为分隔符分割，并在另一个数组的数组和XYZ，QRS有ABCD，MNOP。我尝试以下code：

I have an ArrayList with values like "abcd#xyz" and "mnop#qrs". I want to convert it into an Array and then split it with # as delimiter and have abcd,mnop in an array and xyz,qrs in another array. I tried the following code:

String dsf[] = new String[al.size()];              
for(int i =0;i<al.size();i++){
  dsf[i] = al.get(i);
}

但它没有说Ljava.lang.String; @ 57ba57ba

But it failed saying "Ljava.lang.String;@57ba57ba"

您可以帮我请。

推荐答案

您不必推倒重来，的此处的在的toArray（）方法：

You don't need to reinvent the wheel, here's the toArray() method:

String []dsf = new String[al.size()];
al.toArray(dsf);
