Java OCA OCP Practice Question 3075

Question

For the following enumeration definition, which one of the following prints the value 2 in the console? 

enum Pets { Cat, Dog, Parrot, Chameleon };

a)   System.out.print(Pets.Parrot.ordinal());
b)   System.out.print(Pets.Parrot);
c)   System.out.print(Pets.indexAt("Parrot"));
d)   System.out.print(Pets.Parrot.value());
e)   System.out.print(Pets.Parrot.getInteger());



a)

Note

the ordinal() method prints the position of the enumeration constant within an enumeration and hence it prints 2 for this program.

option b) the call print(Pets.Parrot); prints the string "parrot" to console

options c), d) and e) there are no methods named indexAt(), value(), or getInteger() in Enum
