阅读制表符分隔的文本文件的Java [英] reading tab delimited textfile java

问题描述

10
aaa aaa aaa
bbb bbb bbb
ccc ccc ccc
ddd ddd ddd

我有一个文本文件，我试图用制表符分隔符读取。每当我读取文件时，都会在10之后出现arrayindexoutofbound错误。我在网上搜索并发现我必须在\t后面添加-1，但是我仍然遇到相同的错误。

I have a textfile that Im trying to read with tab delimiters. whenever i read the file, i get an arrayindexoutofbound error after the 10. i search online and found that i have to add a -1 behind the \t but i still get the same error.

 try{
        Scanner scan = new Scanner(new File("1.txt"));
        String line="";
        int readline = Integer.parseInt(scan.nextLine());//

        while (scan.hasNextLine())
        {
            line = scan.nextLine();

            if(line.equals("ccc"))
            {  
                break;
            }
        String[] split=line.split("\t");

            array.add(split);
        } 

推荐答案

如果使用扫描仪此处无需分割，可以使用 next（）

If you are use Scanner here no need to split, you can use next() here as follows

    Scanner sc=new Scanner(new FileReader("D:\\test.txt"));
    while (sc.hasNextLine()){
        System.out.println(sc.next());
    }
