私はいくつかのユニークな価値に基づいてレコードを取得しようとしています。
例; emp名、emp id、empアドレスの値のテーブルがあります。empidに基づいてレコードをフェッチしたいと思います。
これは私が試したコードです。このコードは最初からではなくファイルからデータを読み取ります。
package org.xlsx.read;
import java.io.File;
import java.io.FileInputStream;
import java.util.ArrayList;
import java.util.Iterator;

private void readExcelFile(String fileName) {
/**

List cellDataList = new ArrayList();
try {

HSSFWorkbook workBook = new HSSFWorkbook(fsFileSystem);
HSSFSheet hssfSheet = workBook.getSheetAt(0);
/**

Iterator rowIterator = hssfSheet.rowIterator();
while (rowIterator.hasNext()) {

cellTempList.add(hssfCell);
}
cellDataList.add(cellTempList);
}
} catch (Exception e) {
e.printStackTrace();
}
/**

*/
printToConsole(cellDataList);
}
/**

private void printToConsole(List cellDataList) {
for (int i = 0; i < cellDataList.size(); i++) {

for (int j = 0; j < cellTempList.size(); j++) {

String stringCellValue = hssfCell.toString();
System.out.print(stringCellValue + "\t");
}
System.out.println();
}
}
public static void main(String[] args) {
String fileName = "D:/workspace/ReadExlsx/xlsx/Access_Control_Report_01-04-2012to30-04-2012.xls";
new ExcelSheetReader().readExcelFile(fileName);
}
}
このコードはこのように出力されます。
