閱讀excel的特定行

Question

我想從第二行讀取excel表到第13行，也想獲得相應的列值。請向我提供代碼。 在此先感謝。

Answer 1

您應該試試reading the documentation that comes with Apache POI！

從那裏直接摘自：

// Decide which rows to process 
int rowStart = Math.min(1, sheet.getFirstRowNum()); // 0 based not 1 based rows 
int rowEnd = Math.max(12, sheet.getLastRowNum()); 

for (int rowNum = rowStart; rowNum < rowEnd; rowNum++) { 
    Row r = sheet.getRow(rowNum); 

    int lastColumn = Math.max(r.getLastCellNum(), MY_MINIMUM_COLUMN_COUNT); 

    for (int cn = 0; cn < lastColumn; cn++) { 
     Cell c = r.getCell(cn, Row.RETURN_BLANK_AS_NULL); 
     if (c == null) { 
     // The spreadsheet is empty in this cell 
     } else { 
     // Do something useful with the cell's contents 
     } 
    } 
}

public class ApachePoiDoc 
{ 
    public static void main(String[] args) throws IOException, URISyntaxException 
    { 
    URL url = new URL("http://poi.apache.org/spreadsheet/quick-guide.html#ReadWriteWorkbook"); 
    Desktop.getDesktop().browse(url.toURI()); 
    } 
}
