如何讀取java中excel文件中的列值。

Question

我有在Excel工作表

UserName Password 

Rahul  test123$ 


Manish  Password 

test  newpwd 

所以當我通過值「測試」我應該得到「NEWPWD」作爲輸出。

你能幫我嗎。

您可以使用java的「jxl」庫。

試試這個：

package com.quicklyjava; 

進口JXL *; import jxl.read.biff.BiffException;

import java.io.File; import java.io.IOException;

public static void main(String[] args) { 

    try { 

     //Create a workbook object from the file at specified location. 
     //Change the path of the file as per the location on your computer. 
     Workbook wrk1 = Workbook.getWorkbook(new File("C:/test.xls")); 

     //Obtain the reference to the first sheet in the workbook 
     Sheet sheet1 = wrk1.getSheet(0); 

     //Obtain reference to the Cell using getCell(int col, int row) method of sheet 
     Cell colArow1 = sheet1.getCell(0, 0); 
     Cell colBrow1 = sheet1.getCell(1, 0); 
     Cell colArow2 = sheet1.getCell(0, 1); 

     //Read the contents of the Cell using getContents() method, which will return 
     //it as a String 
     String str_colArow1 = colArow1.getContents(); 
     String str_colBrow1 = colBrow1.getContents(); 
     String str_colArow2 = colArow2.getContents(); 

     //Display the cell contents 
     System.out.println("Contents of cell Col A Row 1: \""+str_colArow1 + "\""); 
     System.out.println("Contents of cell Col B Row 1: \""+str_colBrow1 + "\""); 
     System.out.println("Contents of cell Col A <span class="IL_AD" id="IL_AD12">Row 2</span>: \""+str_colArow2 + "\""); 


    } catch (BiffException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 


}
