java - 想要在java中打印excel中特定单元格的所有行值

Question

获得特定商品名称和价格后，我将其存储在 Excel 工作表中。现在我比较他们的价格并获得最低价格，但是我如何打印最低价格的所有详细信息

我的代码是

public static void getMinPhonePrice() throws Exception {

        File file = new File("C:\\Users\\user\\Desktop\\demo.xlsx"); 

         FileInputStream fs = new FileInputStream(file);

            XSSFWorkbook wb=new XSSFWorkbook(fs);
            String min = wb.getSheetAt(0).getRow(0).getCell(1).getStringCellValue();
            int value_min = Integer.parseInt(min.substring(1).replace(",", ""));

            String getText = null;
            XSSFSheet sh1= wb.getSheetAt(0);
            for(int j=0;j<3;j++) {
             getText =  sh1.getRow(0).getCell(j).getStringCellValue();
             System.out.println(getText);
            }



            for (int i = 1; i <=sh1.getLastRowNum(); i++) {

                String c =  sh1.getRow(i).getCell(1).getStringCellValue();

                int value = Integer.parseInt(c.substring(1).replace(",", ""));

                if(value < value_min) {
                    value_min=value;
                    for(int k=0;k<3;k++) {
                    getText = sh1.getRow(i).getCell(k).getStringCellValue();

                     System.out.println("minimum item detail"+getText);
                    }


            }

        }    

        }
}

but it not printing my minimum item detail

看来您不需要嵌套循环，并且需要将其他单元格存储到字符串变量。请尝试以下代码。

    File file = new File("phone_compare.xlsx");
    FileInputStream fs = new FileInputStream(file);

    XSSFWorkbook wb=new XSSFWorkbook(fs);
    String min = wb.getSheetAt(0).getRow(0).getCell(1).getStringCellValue();
    int value_min = Integer.parseInt(min.substring(1).replace(",", ""));

    String getText = null;

    String str1 =  wb.getSheetAt(0).getRow(0).getCell(0).getStringCellValue();
    String str2 =  wb.getSheetAt(0).getRow(0).getCell(2).getStringCellValue();
    getText = str1 +" " +value_min +" " +str2;
    XSSFSheet sh1= wb.getSheetAt(0);


    for (int i = 0; i <=sh1.getLastRowNum(); i++) {

        String c =  wb.getSheetAt(0).getRow(i).getCell(1).getStringCellValue();

        int value = Integer.parseInt(c.substring(1).replace(",", ""));

        if(value < value_min) {
            value_min=value;
            str1 =  wb.getSheetAt(0).getRow(i).getCell(0).getStringCellValue();
            str2 =  wb.getSheetAt(0).getRow(i).getCell(2).getStringCellValue();
            getText = str1 +" " +value_min +" " +str2;



    }

}    
System.out.println(getText);
}
