Question

Input: String array1[] ={"a","b","c","d","e","f","g","h","i"}
Int array2[]= {0,1,1,0,1,2,2,0,1}
OUTPUT should be; {"a","d","h","b","c","e","i","f","g"}

Answer 1

Its not a trivial thing at all... And the possible solution depends heavily on which java version you have. It involves some conversion to lists, using Collections.sort() and implementing Comparator interface. Check this code and follow the link inside to stackoverflow.. This is just one of many possible solutions.
