Question

Assume the existence of a Phone class with a constructor that accepts two parameters: a string for the phone number followed by a boolean representing whether the phone provides added-value services. Assume a subclass MP3Phone has been defined that has two instance variables: an integer, memorySize, for the size, in megabytes of the phone memory, and a boolean, playsAAC, representing whether the phone is capable of playing AAC-encoded audio files. Write a constructor for MP3Phone that accepts three parameters: a String for the phone number (which is passed up to the Phone constructor, together with the value true for the added-value boolean), and an integer followed by a boolean for the instance variables.

Explanation / Answer

public MP3Phone(String phoneNumber, int mSize, boolean aAC) {

super(phoneNumber, true);//calling super class constructor

//setting remaining values for instance variables

this.mSize = mSize;

AAC = aAC;

}
