Autoboxing - programming concept

Question

1. public static void main(String[] args) 
2. {        
3.    Character s=1;
4.    Float f=1;
5. }

Both the lines 3 and 4 have a wrapper class and compiler performs autoboxing to convert 1 to Character but compiler cannot convert the same 1 to Float. Why?

Answer 1

Float numbers you need to append 'f' or 'F' at end of the number like this Float f=1f; or Float f=1F;
