「Java」「final」 Chapter4 Question12

Given:

final class Drink{
 public void temp() {
 }
}
class Cola{
 public final void ship(int time,int heat) {
 }
 public void cold() {
 }
}
class ColaCompany{
 private Cola c = new Cola();
 public void create() {
  c.ship(15,20);
 }
}
public class Test3 extends Cola{
 public static void main(String[] args) {
  public void ship(int minutes, int temperature) {
  }
  public void addBerry() {
  }
 }
}

Answer:
會造成最大編譯錯誤的是 Test3 類別。
final的方法不能在子類別覆寫

父類別:

public final void ship(int time,int heat)

子類別:

public void ship(int minutes, int temperature)
