Analyze the following code.

public class Test {
public static void main(String[] args) {

Number x = new Integer(3);

System.out.println(x.intValue());

System.out.println((Integer)x.compareTo(new Integer(4)));

}
}

◦ The program has a compile error because intValue is an abstract method in Number.
◦ The program has a compile error because x cannot be cast into Integer.
◦ The program compiles and runs fine.
◦ The program has a compile error because an Integer instance cannot be assigned to a Number variable.
◦ The program has a compile error because the member access operator (.) is executed before the casting operator.
