Analyze the following code:
public class Test extends A {
public static void main(String[] args) {
Test t = new Test();
t.print();
}
}
class A {
String s;
A(String s) {
this.s = s;
}
public void print() {
System.out.println(s);
}
}
B. The program has an implicit default constructor Test(), but it cannot be compiled, because its super class does not have a default constructor. The program would compile if the constructor in the class A were removed.
C. The program would compile if a default constructor A(){ } is added to class A explicitly.
D. The program compiles, but it has a runtime error due to the conflict on the method name print.
The correct answer is BC
Explanation: See the last Note in the section, "Using the super keyword."

- Assume that you are defining a class and you want to implement an ActionListener. You state addActionListener(this); in your class’ constructor. What does this mean?
- In order to implement Comparable in a class, what method(s) must be defined in that class?
- Which of the following interfaces would be used to implement a class that represents a group (or collection) of objects?

- Static methods cannot
- Which of the following methods is a static method? The class in which the method is defined is given in parentheses following the method name.
- An object may be made up of other objects.
- Method decomposition is the process of creating overloaded versions of a method that do the same thing, but operate on different data types.
- The println method on System.out is overloaded.
- A method defined without a return statement will cause a compile error.
- If a method takes a double as a parameter, you could pass it an int as the actual parameter.
- The different versions of an overloaded method are differentiated by their signatures.
- The number and types of the actual parameters must match the number and types of the formal parameters.
- The return statement must be followed a single variable that contains the value to be returned.
