My excel sheet contain 3 cols namely Number, Version, Telephone Num.As shown below Number version tele num. 1 1234 12345 2 abcd 123788 3 1223 17889898
my java code is reading fine when the data of data type are same in cols.
But its giving nullpointerexception when the data of datatype is different in cols.
For example in version cols contain 2 number values and one string values. that time its not reading the version values. Its only working fine version cols contain either all are string values or integer values.But i need to enter both string as well as integer.
