JAVA入门第二季最终练习

/定义一个父元素/
package com.imooc;
//定义一个父类元素
public class Car {
public String Carname;//定义车辆名称
public float Price;//定义车辆价格
public int PeopleNumber;//容纳人的数量
public float Height;//货物数量

}

/定义三个子类元素/
package com.imooc;

public class keche extends Car {
public keche(String Carname,float Price,int PeopleNumber ){
this.Carname = Carname;
this.Price = Price;
this.PeopleNumber = PeopleNumber;
}
//定义一个输出方法
public String toString(){
return ("\t"+Carname+"\t" + Price+"\t\t" + PeopleNumber+"人");
}

}
package com.imooc;

public class huoche extends Car {
public huoche(String Carname,float Price,float Height){

    this.Carname = Carname;
    this.Price = Price;
    this.Height = Height;
}
//定义一个输出方法
public String toString(){
    return ("\t"+Carname +"\t"+ Price +"\t\t"+ Height+"吨");
}

}
package com.imooc;

public class pika extends Car {
public pika(String Carname,float Price,int PeopleNumber,float Height){
this.Carname = Carname;
this.Price = Price;
this.PeopleNumber = PeopleNumber;
this.Height = Height;
}
//定义一个输出方法
public String toString(){
return ("\t"+Carname +"\t"+ Price+"\t\t" + PeopleNumber+"人" + Height+"吨");
}

}
