Answer to Question #282841 in Java | JSP | JSF for karrar.f.a

Question

Consider the following definitions:

void a (Object o, long x, long y) // defn 1

void a (String s, int x, long y) // defn 2

void m (Object o, int x, long y) // defn 3

void a (String s, long I, int y) / defn 4

and suppose you have the following variable declarations:

Object u;

int a;

long b;

For each of the following calls, determine which definitions would match a particular call; also decide whether the call is legal, and if so, which of the preceding definitions is selected:

m (v ,a ,b);

m (v, a, a);

m (v, b, a);

m (v ,b ,b);

m (o, b, b);

m (0, a, a);

Answer 1

All the calls below are calls to the method "m" - hence this definition 3. If we assume that "v" is an object, "a" is an int, "b" is a long, then the first two calls are correct. Otherwise, all calls are invalid.
