Java用分隔符读取大文本文件

问题描述：

我正在尝试读取以下形式的大文本文件:

I'm trying to read a large text file in the form of:

datadfqsjmqfqs+dataqfsdqjsdgjheqf+qsdfklmhvqziolkdsfnqsdfmqdsnfqsdf+qsjfqsdfmsqdjkgfqdsfqdfsqdfqdfssdqdsfqdfsqdsfqdfsqdfs+qsfddkmgqjshfdfhsqdflmlkqsdfqdqdf+

我想在文本文件中将此字符串作为一个大的Java字符串读取.这可能吗?我知道使用split方法.

I want to read this string in the text file as one big java String. Is this possible? I know the use of the split method.

它可以逐行读取它，但我真正需要的是在"+"号处分割此长文本字符串.之后，我想将其存储为数组，arraylist，列表，...

It worked to read it line by line, but what I really need is to split this long text-string at the '+' sign. Afterwards I want to store it as an array, arraylist, list,...

有人可以帮我吗?因为Internet上的所有信息都只是关于逐行读取文件的信息. 预先感谢！

Can anyone help me with this? Because every information on the internet is just about reading a file line by line. Thanks in advance!

答

您可以使用BufferedReader或任何IO类读取文件.假设您在testing.txt文件中具有该String，然后可以从文件中读取每一行用分隔符(+)分割它.并遍历数组并打印.

You can read file using BufferedReader or any IO-classes.suppose you have that String in testing.txt file then by reading each line from file you can split it by separator (+). and iterate over array and print.

BufferedReader br = null;
    try {
        String sCurrentLine;
        br = new BufferedReader(new FileReader("C:\\testing.txt"));//file name with path
        while ((sCurrentLine = br.readLine()) != null) {
               String[] strArr = sCurrentLine.split("\\+");
               for(String str:strArr){
                    System.out.println(str);
                      }
            }

        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                if (br != null)br.close();
            } catch (IOException ex) {
                ex.printStackTrace();
            }
        }
