AP Computer Science A· difficulty 2/5

public class Counter {
    private int count;
    public Counter() { count = 0; }
    public void inc() { count++; }
    public int getCount() { return count; }
}
// ...
Counter c = new Counter();
c.inc(); c.inc(); c.inc();
System.out.println(c.getCount());

What is printed?

A
$3$
check_circle
B
$0$
C
$1$
D
$Compile-time error$

Explanation

The default constructor sets count to 0; inc() is called three times, so count becomes 3.
