Consider the following code snippet. public interface Measurable { double getMeasure): } public class Coin implements Measurable { public Coin(double aValue. String aName) { .-- } public double getMeasure) { return value; } } public class BankAccount implements Measurable { public BankAccount(double initBalance) {.. } public void getMeasure) { return balance; } Which of the following statements is correct? Justify your choice. a) Coin dime = new Coin(0.1, "dime"); BankAccount b = (Measureable)dime; b) Measureable m=new BankAccount(1000); BankAccount b =m; c) Coin dime = new Coin(0.1, "dime"); Measurable m = dime; d) Measurable m =new Coin(0.1, "dime"); Coin dime = m;
