第4次作业类测试代码+141+汤阳斌

1.类图：

2.界面和相应功能：

计算销售额最大的配件

//销售额最大的配件
public static String mostSale(int hp, int mpc, int cpsp){
    String mostsale = null;
    int my_hp = 0,my_mpc = 0,my_cpsp = 0;
    my_hp = hp*80;
    my_mpc = mpc * 10;
    my_cpsp = cpsp * 8;
    if(my_hp > my_mpc){
        if(my_hp > my_cpsp){
            mostsale = "耳机";
        } else{
            mostsale = "手机贴膜";
        }
    }else{
        if(my_mpc > my_cpsp){
            mostsale = "手机壳";
        }else{
            mostsale = "手机贴膜";
        }
    }
     
    return mostsale;
     
}

计算销售数量差最大：

//销售配件最多与最少之差
public static int diffSale(int hp, int mpc, int cpsp){
    int diffsale = 0;
    int df1 = Math.abs(hp - mpc);
    int df2 = Math.abs(hp - cpsp);
    int df3 = Math.abs(mpc - cpsp);
    diffsale = df1 > df2 ? df1:df2;
    diffsale = diffsale > df3 ? diffsale : df3;
    return diffsale;
}
