我想要实现的是从Excel表格（保存在Txt，制表符分隔）中逐行读取数据，每个单独的列是我想要存储在数组中的不同数据。
我尝试了不同的方式..我甚至从互联网上下载了CSVReader类，但它没有用。 至少这次它的阅读真正的人物而不是西伯利亚。
我现在的版本是使用bufferedReader和String Tokenizer。 但它没有正确阅读。
以下是代码：
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;
import java.util.StringTokenizer;
import com.csvreader.CsvReader;
import au.com.bytecode.opencsv.CSVReader;
public class excelToText{
public static void main(String[] args) throws IOException {
try
{
//csv file containing data
BufferedReader CSVFile = new BufferedReader(new FileReader("C:/Users/nhajjar/workspace/MB/src/yoyo.txt"));
// Read first line.
String dataRow;
int lineNumber = 0;
while ((dataRow = CSVFile.readLine() )!= null)
{
String [] dataArray;
lineNumber++;
String delimiter = "\t";
/* given string will be split by the argument delimiter provided. */
dataArray = dataRow.split(delimiter);
/* print substrings */
// for（int i = 0; i＆lt; dataArray.length; i ++） // System.out.println（dataArray [i]）;
String PrinterName = dataArray[0];
String Model = dataArray[1];
String IP = dataArray[2];
String Location = dataArray[3];
String Department = dataArray[4];
String PrimServer = dataArray[5];
String SecServer = dataArray[6];
String ShareName = dataArray[7];
String GroupNamePrefix = dataArray[8];
String GroupNameSuffix = dataArray[9];
String GroupNameFinal = dataArray[10];
String WSPPrefix = dataArray[11];
String WSPFull = dataArray[12];
String PrimWSP = dataArray[13];
String SecWSP = dataArray[14];
System.out.println("PrinterName is : " + PrinterName);
System.out.println("Model is : " + Model);
System.out.println("IP is : " + IP);
System.out.println("Location is : " + Location);
System.out.println("Department is : " + Department);
System.out.println("PrimServer is : " + PrimServer);
System.out.println("SecServer is : " + SecServer);
System.out.println("ShareName is : " + ShareName);
System.out.println("GroupNamePrefix is : " + GroupNamePrefix);
System.out.println("GroupNameSuffix is : " + GroupNameSuffix);
System.out.println("GroupNameFinal is : " + GroupNameFinal);
System.out.println("WSPPrefix is : " + WSPPrefix);
System.out.println("WSPFull is : " + WSPFull);
System.out.println("PrimWSP is : " + PrimWSP);
System.out.println("PrimWSP is : " + PrimWSP);
System.out.println("SecWSP is : " + SecWSP);
/*//writing file for ones that were not sent out.
File file = new File("write.txt");
BufferedWriter output = new BufferedWriter(new FileWriter(file));
*/
}
CSVFile.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch(Exception e) {
System.out.println("Exception while reading/writing csv file: " + e);
}// end Exceptions
}// end try block
}

Exception while reading/writing csv file: java.lang.ArrayIndexOutOfBoundsException: 7
注意：我关闭了输出。这些'Null块'更多......
答案 0 :(得分：2)
看起来你过于复杂了。 CSV文件具有逗号分隔值。因此，您的文件数据应如下所示：
第1行：细胞1，细胞2，细胞3，细胞4等......
第2行：第2行的单元格1，第2行的第2单元格等......
您使用制表符分隔文件，因此需要在选项卡上进行拆分
//Read first line
String dataRow;
int lineNumber = 0;
while((dataRow = CSVFile.readline()) != null)
{
String [] dataArray;
lineNumber++;
String delimiter = "\t";
dataArray = dataRow.split(delimiter); //Now dataArray contains all the tab delimited cells that were on line one of the .txt file
//Start assigning the information to your variables since it is stored in dataArray
String PrinterName = dataArray[0];//This would assign the first cell (row 1, column 1 in excel) that was read from the text file. From looking at your input this should be "Printer name"
String Model = dataArray[1];
String IP = dataArray[2];
//etc...Assign the rest
//Print your output
//Do anything else you need to do
}//end the while loop
以下是一些消息来源：

注意：此示例更接近您正在使用的“\ t”而不是“，”： http://www.daniweb.com/software-development/java/threads/17262/reading-in-a-.csv-file-and-loading-the-data-into-an-array
希望这会有所帮助
答案 1 :(得分：0)
标记只按空格和加号划分。这是因为StringTokenizer的第二个参数不允许正则表达式。尝试使用"\t"字段似乎真正分开。
顺便说一下，每行真的不需要100个字符串数组。
答案 2 :(得分：0)
我建议使用String.split()函数，因为这会大大简化您的代码。
答案 3 :(得分：0)
我不建议您自己使用.split或StringTokenizer类拆分数据。他们不考虑现场报价等...
使用像（如上所述）OpenCSV或StrTokenizer（commons-lang的一部分）这样的库来为您进行解析。
使用制表符分隔的解析器的StrTokenizer示例：
StrTokenizer tokenizer = StrTokenizer.getTSVInstance();
while ( (line = ...) != null) {
tokenizer.reset(line);
String tokArray[] = tokenizer.getTokenArray();
}
