Given the following code, which statements concerning the objects referenced through the member variables i, j and k are true, given that any thread may call the methods a, b and c at any time? ()
class Counter { int v = 0;
synchronized void inc() { v++; }
synchronized void dec() { v--; }
}
public class Q7ed5 {
Counter i;
Counter j;
Counter k;
public synchronized void a() {
i.inc();
System.out.println("a");
i.dec(); }
public synchronized void b() {
i.inc();
j.inc();
k.inc();
System.out.println("b");
i.dec();
j.dec();
k.dec(); }
public void c() {
k.inc();
System.out.println("c");
k.dec();
}
}
A.i.v is guaranteed always to be 0 or 1.
B.j.v is guaranteed always to be 0 or 1.
C.k.v is guaranteed always to be 0 or 1
D.j.v will always be greater than or equal to k.v at any give time.
E.k.v will always be greater than or equal to j.v at any give time.
