deleting blank row or null row in java ( HSSF)

[swapnil kataria]

i am trying to read Excel Sheet in java,

autally it has 4 rows containing data,

but when I tries to get value of total no. of rows by using sheet.getLastRowNum()

it returns 9,

then i print the row reference in a loop, it shows row no. 8 and 9 as null but from 5 to 9 each row is actually blank,
for 5,6,7 it prints object value
for 8,9 it prints null,

is there is way to remove such rows before start reading
