我需要根据找到的行数据总结 Excel Column(1) 值。
我的excel文件如下：
column(0) column(1)
Row[0] ECIN - INPUT VALUE (ADD) NetTradeAllowanceAmount = -600.00
Row[1] ECIN - INPUT VALUE (ADD) CashDownPayment = 300.00
Row[2] ECIN - INPUT VALUE (ADD) OtherDownPaymentAmount = PATH DOES NOT EXIST
Row[3] ECIN - INPUT VALUE (ADD) CashDownPayment = 400.00
Row[4] ECIN - INPUT VALUE (SUB) OtherDownPaymentAmount = PATH DOES NOT EXIST
Row[5] ECIN - INPUT VALUE (SUB) ManufacturerRebateAmount = 500.00
Row[6] ECIN - INPUT VALUE (SUB) DeferredDownPaymentAmount = -700.00
Row[7] ECIN - INPUT VALUE (SUB) DeferredDownPaymentAmount = 900.00
首先，我需要查看 Column(0)，所有行：
1.add the column(1) values having rows (ADD) data. (eg: SUM= 300.00 + 400.00 - 600.00 = 700.00 - 600.00 = 100.00)
2.add the column(1) values having rows (SUB) data. (eg: SUM=500.00 - 700.00 + 900.00 = 1400.00 - 700.00 = 700.00)
3.then subtract above two SUMs. (eg: 100.00 - 700.00 = 600.00)
我应该将此结果保存在某个变量中，并将该值记录在其他单元格中。
注意：程序不应考虑 value = PATH DOES NOT EXIST，即使行包含数据（SUB / ADD）。
在某种程度上，我已经编写了代码。如下：
import java.io.*;
import java.util.*;
import org.apache.poi.hssf.usermodel.*;
import org.apache.poi.ss.usermodel.*;
public class Hai
{
public static void main(String[] args)
{
try
{
FileInputStream file = new FileInputStream(new File("C:/Users/Excel.xls"));
HSSFWorkbook workbook = new HSSFWorkbook(file);
HSSFSheet sheet = workbook.getSheetAt(5);
Iterator<Row> rowIterator = sheet.iterator();
while(rowIterator.hasNext())
{
Row row = rowIterator.next();
Iterator<Cell> cellIterator = row.cellIterator();
while(cellIterator.hasNext())
{
Cell cell = cellIterator.next();
String Tag=cell.getStringCellValue().toString();
cell = row.getCell(0+1);
if(cell !=null)
if(Tag.contains("ADD"))
{
String Tag1=cell.getStringCellValue().toString();
String[] s= Tag1.split("=");
//System.out.println(s[1]);
if(!s[1].contains("PATH DOES NOT EXIST"))
{
System.out.println(s[1].trim());
}
}
else if(Tag.contains("SUB"))
{
String Tag1=cell.getStringCellValue().toString();
String[] s= Tag1.split("=");
if(!s[1].contains("PATH DOES NOT EXIST"))
{
System.out.println(s[1].trim());
}
}
}
}
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
我得到的输出如下：
-600.00
300.00
400.00
500.00
-700.00
900.00
上面的值都是字符串格式的，我想总结一下这些值。请帮我！
我已将上述值转换为 Flaot，如下所示：
Float foo = Float.parseFloat(s[1].trim());
我得到的输出是：
-600.0
300.0
400.0
我想得到两位小数并总结这些值。我无法总结这些值。
是不是这样

帮我解决这个问题。
