Question
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 getMeasurel)
{
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;
