Question

11. Consider this class: class Node implements Comparable T> t public int compare To(T obj) I/ Will the following code compile? If not, why? Node-String> node = new Node(); Comparable comp node; 12. A method greatestCommonDivisor returns 1 if its two integer arguments are relatively prime. How do you invoke the following method to find the first integer in a list that is relatively prime to a list of specified integers? public staticT int firstRelativePrime(List T> list, int begin, int end, UnaryPredicateT p) Note that two integers a and b are relatively prime if gcd(a, b) -1, where gcd is short for greatest common divisor

Explanation / Answer

11.

compiles perfectly , first the class implements the compareTo method of the comparable interface and then an instance of the class is assigned to a reference of type Comparable<String> which is totally acceptable.
