由线到数组存储文本文件内容行 [英] Store text file content line by line into array

问题描述

一切，我现在面临着存储文本文件中的内容放入数组不知道的问题。
情况是这样，文本文件的内容：

  ABC1
XYZ2
rxy3
 

我想用线将它们存储到阵列产品线，这可能吗？我希望是这样的：

 改编[0] = ABC1
改编[1] = XYZ2
ARR [2] = rxy3
 

我已经尝试这样的事情，但似乎没有为我工作。如果有人能帮助我，真的非常感谢。

在code是：

 中的BufferedReader =新的BufferedReader（新的FileReader（路径/ /文））;
        字符串str;        而（（海峡= in.readLine（））！= NULL）{
            的String [] = ARR str.split（）;
            的for（int i = 0; I＆LT; str.length（）;我++）{
                改编[I] = in.readLine（）;
            }
        }
 

解决方案

我会推荐使用的ArrayList ，用于处理动态调整大小，而数组将需要一个定义的大小前面，你可能不知道。您可以随时关闭该列表返回到一个数组。

 中的BufferedReader =新的BufferedReader（新的FileReader（路径/ /文））;
        字符串str;        清单＆LT;串GT;名单=新的ArrayList＆LT;串GT;（）;
        而（（海峡= in.readLine（））！= NULL）{
            list.add（STR）;
        }        的String [] = stringArr list.toArray（新的String [0]）;
 

all,I'm now facing the problem of no idea on storing the content in text file into the array. The situation is like, text file content:

abc1
xyz2
rxy3

I wish to store them into array line by line, is that possible? What I expect is like this:

arr[0] = abc1
arr[1] = xyz2
arr[2] = rxy3

I've try something like this, but seem like not work for me. If anyone can help me, really thanks a lot.

The code is:

BufferedReader in = new BufferedReader(new FileReader("path/of/text"));
        String str;

        while((str = in.readLine()) != null){
            String[] arr = str.split(" ");
            for(int i=0 ; i<str.length() ; i++){
                arr[i] = in.readLine();
            }
        }

解决方案

I would recommend using an ArrayList, which handles dynamic sizing, whereas an array will require a defined size up front, which you may not know. You can always turn the list back into an array.

        BufferedReader in = new BufferedReader(new FileReader("path/of/text"));
        String str;

        List<String> list = new ArrayList<String>();
        while((str = in.readLine()) != null){
            list.add(str);
        }

        String[] stringArr = list.toArray(new String[0]);
