Questions?

[Raju Uprety]

I have a Q?
interface MyInterfce{
1 int x=1;
2
}
What can be added on line 2? Choose (Three)
I choose 2, 5, 9, Is it right?
I guess an interace can not have access modifier. native is only for method. I think I can't use abstract for variable.
My guess final is right one? I still need to pick two more, so I choose 3, 9.
Anybody figure out which one is right one?
1) public int x=1;
2)protected int x=1;
3)transit int x=1;
4)private int x=1;
5)final int x=1;
6)native int x=1;
7)abstract int x=1;
9)volatile int x=1;

Hi Raju,
If you try compiling the code with the various options you get the following results:

interface MyInterface {
    int x = 1;
    
    public int y=1;
//    protected int x=1;        // protected not allowed
//    transient int x=1;        // transient not allowed
//    private int x=1;          // private not allowed
    final int z=1;
//    native int x=1;           // native not allowed
//    abstract int x=1;         // abstract not allowed
//   volatile int x=1;          // volatile not allowed
    
}

Note, you cannot continue to use 'x' as the variable name; doing so produces a compile errror 'x already defined'.
Hope that helps.
