定义一个学生类(student)

Question

定义一个学生类(student)，成员变量：id(学号),name(姓名),fee(学费/年),成员方法：获取学费getFee（）；

定义一个在职研究生类(Graduate),它继承学生类，成员变量：pay(工资/月),成员方法：获取工资getPay()；

创建一个Graduate类的对象,统计他的年收入，如果年收入减去学费不足12000元，则输出“you need a loan”(需要贷款),否则输出“your pay is enough!”

Answer 1

public class Student {
	private int id;
	private String name;
	private float fee;
	
	public void setFee(float fee) {
		this.fee = fee;
	}
	
	public float getFee() {
		return fee;
	}
}


public class Graduate extends Student{
	private float pay;
	
	public void setPay(float pay) {
		this.pay = pay;
	}
	
	public float getPay() {
		return pay;
	}
}

public static void main(String[] args) {
		// TODO Auto-generated method stub
		Graduate graduate = new Graduate();
		graduate.setPay(20000);
		graduate.setFee(5000);
		if(graduate.getPay()-graduate.getFee()<12000) {
			System.out.println("you need a loan");
		}else {
			System.out.println("your pay is enough");
		}
	}
