Question

Consider the following code snippet, public Interface Measurable {double getMeasure(); public class Coin implements Measurable public double getKeaaure() return value;}} public class DataSet {public void add {} {} public class BankAccount {public void add {} {}} Which of the following statements is correct? Explain your answer. Coin = new Coin(0.1, "dime"); Measurable x - dime; Coin dime = new Coint (0.l, -dime"); Dataset x = dime; Coin dime = new Coin (0.l, = dime"); DataSet x = = (Measureable) dime; d) Coin dime = new Coint (0.l, "dime"); BankAccount x = dime;

Explanation / Answer

a)
   Coin dime = new Coin(0.1, "dime");
   Measurable x = dime;

   This is VALID, because Coin class is implementer of Measurable iterface

   So Measurable can hold the object of type Coin

Others are not valid as Coin class is not child class or implementer class of

Dataset and BankAccount
