java.lang.NumberFormatException: For input string: ""

[Farakh khan]

Hello,

If month or year is null then the following code throws exception
java.lang.NumberFormatException: For input string: ""

	String errorCheck=cm.addExpErrorCheck( 	employer, countryId, bType, sMonth, sYear, 
						eMonth, eYear, jobTitle, shortDesc, sEquipments);

--------------------------------------------------------------

	if(DateManager.dateTest("01",sMonth,sYear,"01",eMonth,eYear).equals("1")){
	error[10]="Start date cannot be greater than end date or today's date";
	}
--------------------------------------------------------------


	public static String dateTest(	String days,
					String months,
					String year,

					String days1,
					String months1,
					String year1){

	
	Calendar cal = new GregorianCalendar();

	int year0 	= cal.get(Calendar.YEAR);             
    	int month0 	= cal.get(Calendar.MONTH);           
    	int day0 	= cal.get(Calendar.DAY_OF_MONTH);      

	String flag="";	

	int dayOfMonth	=Integer.parseInt(days);
	int month	=Integer.parseInt(months);
	int years	=Integer.parseInt(year);

	int dayOfMonth1	=Integer.parseInt(days1);
	int month1	=Integer.parseInt(months1);
	int years1	=Integer.parseInt(year1);

	
	
        GregorianCalendar gc1 =    
            new GregorianCalendar(years, month, dayOfMonth);   
       	 
        GregorianCalendar gc2 =    
            new GregorianCalendar(years1, month1, dayOfMonth1);   

	GregorianCalendar gc3 =    
            new GregorianCalendar(year0, month0, day0);   


	if(gc1.after(gc2))
	{
	flag="1";
	}	
	else if(gc2.after(gc3))
	{
	flag="1";
	}	
	else{
	flag="0";
	}


	return flag;
	
	}

Thanks in anticipation

Not sure if there is a question here... but if you are asking if the parseInt() method throws a number format exception for empty strings, then "yes".

If the passed String were not properly formatted, then NumberFormatException will be thrown. "" is not a properly formatted number.
