        this.annualIncome = annualIncome;
        this.downPayment = downPayment;
        this.status = false;
    }

    public String getName() {
        return name;
    }

    public int getCreditScore() {
        return creditScore;
    }

    public long getAnnualIncome() {
        return annualIncome;
    }

    public int getDownPayment() {
        return downPayment;
    }

    public void setStatus(boolean status) { …

这是调用第二个类来运行的代码.
