推荐回答（2个）

回答1：

把父类的方法改成带参数的方法即可啊public double calculateMonthlyInterest(double accountBalance ) { return accountBalance * annualInterestRate/12; } 子类调用父类方法: super.calculateMonthlyInterest(accountBalance);

回答2：

父类中的方法可定义为：public double calculateMonthlyInterest(double accountBalance ) { return accountBalance * annualInterestRate/12; }在子类的构造方法中第一个语句使用：super.calculateMonthlyInterest(accountBalance);
