using comparator with array of primitives ?

[Mohit G Gupta]

why Comparator cannot be used to sort a primitive array ?

why Comparators cannot be used when searching arrays of primitives ?

[Deepak Bala]

Primitives cannot be compared with a Comparator since the comparison is between typed objects. Primitives are not objects

[Christophe Verré]

Did you try to see what happens ?

primitive type inbuild have the compare method implemented.............
so there is no need to do that

[Deepak Bala]

Primitives do not have methods

yes....deepak you are right..............sorry guys................
the fact is that why primitives doesnot required comparator is.............
because Array.sort() method is overloaded millions times to provide a couple of methods to sort the primitives.............

so there is no need to sort() primitives and if you are trying to do that you will get exception...(i am not sure which error may be compile time or runtime......but most probably you will get runtime exception because sort is done at runtime.)


above explaination which i give is for string class................it implements comparable interface so there is no need to sort it.......
it automatically do that in increasing order.............
