用Java实现excel转txt

import java.io.BufferedWriter;

import java.io.FileWriter;
import java.io.IOException;

import jxl.Sheet;
import jxl.Workbook;

            Sheet sheet = workbook.getSheet(0);
            //转成txt要保存的位置以及文件名
            File file = new File("e:/1.txt");
            FileWriter fw = new FileWriter(file);
            BufferedWriter bw = new BufferedWriter(fw);
            // j为行数，getCell("列号","行号")

                    String s = c.getContents();
