1.7Oob同类中不同方法间的互相调用

import java.util.Scanner;

public class Bill {
    public static final double RATE=150.0;     这里没有创建getter和setter方法，直接创建了一个方法体为参数接收参数值，
    private int hours;　　　　　　　　　　　　　　　　　
    private int minutes;
    private double fee;

    public void inputTimeWorked() {
        System.out.println("Enther");
        System.out.println("followedr");
        Scanner Keyboard =new Scanner(System.in);
        hours=Keyboard.nextInt();
        minutes=Keyboard.nextInt();
    }
    private double computeFee(int hoursWorked,int minutesWorked) {
        minutesWorked=hoursWorked*60+minutesWorked;
        int quarterHours=minutesWorked/15;
        return quarterHours*RATE;
    }
    public void updateFee() {　　　　　　　　　　　　这里调用updateFee方法 这里的hours和minutes是当前类的变量
        fee=computeFee(hours,minutes);
    }
    public void outputBill() {
        System.out.println("time worked:");
        System.out.println(hours+"hours and"+minutes+"minutes");
        System.out.println("rate"+RATE+"per quarter hour");
        System.out.println("amout due"+fee);
    }
    public static void main(String[] args) {
        System.out.println("welcome to:");
        System.out.println("Deway:");
        Bill yourBill=new Bill();
        yourBill.inputTimeWorked();
        //yourBill.updateFee();
        yourBill.outputBill();
        System.out.println("we have:");
        System.out.println("it has:");

    }

}
