我用

编写类似的阅读tsv文件

datarow.splite("\t");

但如果tsv文件包含"\t"，则显示\t表示正在将\t作为普通文本

public class Tsv_read{

public static void main(String[] arg) throws Exception {

BufferedReader TSVFile = 
    new BufferedReader(new FileReader("users.tsv"));

String dataRow = TSVFile.readLine(); // Read first line.

while (dataRow != null){
String[] dataArray = dataRow.split("\t");
for (String item:dataArray) { 
  System.out.print(item + "  "); 
  }
System.out.println(); // Print the data line.
dataRow = TSVFile.readLine(); // Read next line of data.
}
// Close the file once all data has been read.
TSVFile.close();

// End the printout with a blank line.
System.out.println();

 } //main()
} // TSVRead

Answer 1

不要尝试手动解析TSV，因为有一些极端情况，例如转义/转义，更不用说大文件的性能/内存问题＆amp;缺乏灵活性（特别是转换值，选择要读取的列和按什么顺序等）。

试试uniVocity-parser's TSV parser。这是一个简单的例子：

TsvParserSettings settings = new TsvParserSettings(); //you will find MANY options here

TsvParser parser = new TsvParser(settings);

// parses all rows in one go.
List<String[]> allRows = parser.parseAll(YOUR_INPUT_HERE);

试试这段代码我希望能帮到你

import java.io.BufferedReader;
import java.io.FileReader;
import java.util.ArrayList;
import java.util.List;
import java.util.StringTokenizer;

public class Tsv_read{

    public static void main(String[] arg) throws Exception {

        StringTokenizer st ;
        BufferedReader TSVFile = new BufferedReader(new FileReader("users.tsv"));
        String dataRow = TSVFile.readLine(); // Read first line.

        while (dataRow != null){
            st = new StringTokenizer(dataRow,"\t");
            List<String>dataArray = new ArrayList<String>() ;
            while(st.hasMoreElements()){
                dataArray.add(st.nextElement().toString());
            }
            for (String item:dataArray) { 
                System.out.print(item + "  "); 
            }
            System.out.println(); // Print the data line.
            dataRow = TSVFile.readLine(); // Read next line of data.
        }
        // Close the file once all data has been read.
        TSVFile.close();

        // End the printout with a blank line.
        System.out.println();

    } //main()
} // TSVRead

它正在使用stringtokenizer

 while (dataRow != null){
        st = new StringTokenizer(dataRow,"\\t");
        while(st.hasMoreElements()){
            dataArray.add(st.nextElement().toString());
        }
