Read data from xlsx using JAVA apache poi fails to read the last cell of a row

Below is the code to read data from 9 excel cells.

Excel data format is at the end of code.
It has two rows.
It never reads the last cells data,tried all the combinations

XLS sheet data has two rows like this( NOte : Status cell is empty)

S.No.| ID |First Name |Last Name |Contact number |Email id |Usermode |channel |Status
1 test@test.com Ram singh 45455666 xyz@test.com Password XYZ empty cell

Option 1
you have checked cell null condition but not "" this condition.There might be chances that if you have added data manually to excel sheet that cell is not BLANK and have some space etc. Try to Add this

if((row.getCell(k))!= ""){
//now check column is 8
if(k==8)

Option 2
That cell type might be UNKNOWN so add this case as well

case Cell.CellType _NONE 

Option 3
Your are expecting that cell type as blank but it could be either numeric or string so try to add K==8 condition in both of this switch case or find out specific type of that cell first.

Actually it gives a NULL pointer exception when a cell is blank or empty or no values in it when using getcell(int k);,So the solution is before the if((cell=row.getCell(k))!=null) add a line to convert the null to blank like this
cell=row.getcell(k,row.CREATE_NULL_AS_BLANK).
