Analyze the following code:

public class Test {
public static void main(String[] args) {
​Object a1 = new A();
​Object a2 = new Object();
​System.out.println(a1);
​System.out.println(a2);
}
}

class A {
int x;

public String toString() {
​return "A's x is " + x;
}
}

◦ When executing System.out.println(a2), the toString() method in the Object class is invoked.
◦ When executing System.out.println(a1), the toString() method in the A class is invoked.
◦ When executing System.out.println(a1), the toString() method in the Object class is invoked.
◦ The program cannot be compiled, because System.out.println(a1) is wrong and it should be replaced by System.out.println(a1.toString());
