question 44)

what will the following code print out?

public class oct{
    public static void main(string argv[]){
 oct o = new oct();
 o.amethod();
    }
    public void amethod(){
 int oi= 012;
 system.out.println(oi);
    }
}

1)12
2)012
3)10
4)10.0 

question 45

what will happen when you try compiling and running this code?

public class ref{
    public static void main(string argv[]){
 ref r = new ref();
 r.amethod(r);
    }
    public void amethod(ref r){
 int i=99;
 multi(r);
 system.out.println(i);
    }
    public void multi(ref r){
 r.i = r.i*2;
    }
}

1) error at compile time
2) an output of 99
3) an output of 198
4) an error at runtime
