Yinliao类代码：

package org.hanqi.pn0120;

public class Yinliao {

    private String mingcheng;
    private double jiage;
    public String getMingcheng() {
        return mingcheng;
    }
    public void setMingcheng(String mingcheng) {
        this.mingcheng = mingcheng;
    }
    public double getJiage() {
        return jiage;
    }
    public void setJiage(double jiage) {
        this.jiage = jiage;
    }
    public Yinliao(String mingcheng, double jiage) {
        super();
        this.mingcheng = mingcheng;
        this.jiage = jiage;
    }
    public void drink()
    {
        System.out.println("我要喝"+this.mingcheng);
        System.out.println(this.mingcheng+"的价格是："+this.jiage);
    }
}

package org.hanqi.pn0120;

public class Testdrink {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Yinliao mydrink=new Yinliao("橙汁",3);
        mydrink.drink();
