hi guys

have to write a program calculating student and teacher flights and accomodation and its more complicated but i just need to check something before i get stuck in

i have this coded so far:



firstly why can you not multiply an int variable by a float? im getting an error

so if a ihave a value of people which is int ..say 23
and a flight price of 236.77 etc
do i need to convert the people to a float?

thanks

Jon, I suspect  that your problem "went away" because you converted the input values from strings to numbers.  For example, the value of numberOfNights in line 25 is a string, not a number.  So the problem may have been that you were attempting to multiply a string by a float, rather than an integer by a float.  Does that make sense?
 
It is sorta covered in the JavaRanch Style Guide.
