ENUM and Switch
What will be the output of the following program?
enum Employees {
    TCS, WIPRO, Cerone, Infosys, Polaris
public class SwitchCase {
    public static void main(String args[]) {
        Employees student;
        student = Employees.Cerone;
        switch (student) {
            case TCS :
                System.out.print("Ravi is working here.");
            case WIPRO :
                System.out.print("Raghu is working here.");
            case Cerone :
                System.out.print("Ramesh is working here.");
            case Infosys :
                System.out.print("Rakesh is working here.");
            case Polaris :
                System.out.print("Ram is working here.");
            case HCL :
                System.out.print("Ram is working here.");

A. Ramesh is working here.
B. Some other output
C. Compilation Error because the Employeeenum declared outside the class SwitchCase.
D. Compilation Error or Runtime Error for some other reason.

User comments below. All of them might not be correct.

enum is user defined type
enum members have equivalent integer values (by default starts from 0)
TCS=0 WIPRO=1 Cerone=2.. and so on
Also conversion from enum-->to-->int is automatic
(int-->enum requires casting)
output will be : Ramesh is working ( 2)
break; will take control flow out

Ans is A as employees.cerone value is assigned to student i.e 2 and case cerone is executed and break stmt is executed and sos stmt is printed (Tushar has already won this week )

^ enum can take only one of the 5 defined values HCL is not defined

Posted by Tushar Ghude    2014-07-31 13:21:01

As Tushar Ghude pointed out, it fails to compile because HCL is not defined.

Thanks for the feedback Mani Deep, we will try to give more details when rejecting the answer.
