Question

I tried below code but no good, I am unable to create excel document, open and close it.

package tests;

import java.io.*;

import org.apache.poi.ss.usermodel.Workbook;  
import org.apache.poi.xssf.util.*;  
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

public class Xls_Reader  {


Workbook wb = new XSSFWorkbook();  
FileOutputStream fileOut = new FileOutputStream("workbook.xlsx");

}

I am getting following error:

Default constructor can not handle exception type FileNotFoundException 
    thrown by implicit super constructor . Must define an explicit constructor.

Can someone help me understand the concept of creating excel file with POI API?
