Question

当我尝试从main方法执行以下代码时，我收到Stream Closed错误。但是我没有关闭代码中的任何流。我什至试图在for循环后关闭工作簿，但仍然得到相同的结果错误。谁能帮助我解决这个问题？

Code: 

public class ExcelCompare
{
    public void compare(String path1, String path2 ) throws IOException
    {
    FileInputStream fs = new FileInputStream(path1);
    XSSFWorkbook wk = new XSSFWorkbook(fs);
    XSSFSheet s = wk.getSheet("Sheet1");
    int rcount = s.getPhysicalNumberOfRows();
    FileInputStream fs1 = new FileInputStream(path2);
    XSSFWorkbook wk1 = new XSSFWorkbook(fs);
    XSSFSheet s1 = wk.getSheet("Sheet1");
    for(int i=1; i<rcount; i++)
    {
        XSSFRow r = s.getRow(i);
        XSSFRow r1 = s1.getRow(i);
        int ccount = r.getPhysicalNumberOfCells();
        for(int j=0;j<=ccount;j++)
        {
            XSSFCell c = r.getCell(j);
            XSSFCell c1 = r1.getCell(j);
            if(c.getCellType()==1)
            {
                if((c.getStringCellValue()).equals(c1.getStringCellValue()))
                    {

                    }
            }

            else
            {
                System.out.println("value mismatch"+ c.getStringCellValue() +c.getStringCellValue());
            }
        }
    }

    }

}

更新代码中的以下行即可使用

    FileInputStream fs1 = new FileInputStream(path2);
    XSSFWorkbook wk1 = new XSSFWorkbook(fs1);
    XSSFSheet s1 = wk1.getSheet("Sheet1");

线程“主”中的异常java.io.IOException：流已关闭
