如何读取特定行和列的Excel工作表

Question

我想从特定的行号读取Excel表格，只想要一些特定的列值。我尝试了很多东西，但是我没有按预期获得正确的输出。 以下是我的代码段：

public class ReadExcel {

File src=new File("F:\\ucd\\UAT_Patch_31012018.xlsx");
XSSFWorkbook wb;
XSSFSheet Sheet1;
FileOutputStream fileOut;

public void ReadExcel1() throws Exception{
    FileInputStream fis = new FileInputStream(src);
    XSSFWorkbook wb=new XSSFWorkbook(fis);
    XSSFSheet Sheet1=wb.getSheetAt(0);

    int rowcount=Sheet1.getPhysicalNumberOfRows();
    int colcount=Sheet1.getRow(0).getPhysicalNumberOfCells();

    for(int i=6;i<=9;i++){
        for(int j=0;j<=rowcount;j++){
            String testdata1=Sheet1.getRow(i).getCell(j).getStringCellValue();
            System.out.println(testdata1);
        }
    }
}

public static void main(String args[]) throws Exception{
ReadExcel read=new ReadExcel();
read.ReadExcel1();
}
}

Excel文件格式：

File Name     Target Server   Target Path
abc/Abc.txt    10.0.43.101  /home/urbancode/UrbanCode/Test/DeployableComponent/abc
pqr/Abc.txt               /home/urbancode/UrbanCode/Test/DeployableComponent/pqr
xyz/Abc.txt                 /home/urbancode/UrbanCode/Test/DeployableComponent/xyz

我想将输出保存在temp.txt文件中，如下所示：

 abc/Abc.txt;/home/urbancode/UrbanCode/Test/DeployableComponent/abc
 pqr/Abc.txt;/home/urbancode/UrbanCode/Test/DeployableComponent/pqr
