public class Phone {

    public final void recharge(final Integer recharge){
        if(recharge != 5){
            throw new RuntimeException("电池可能会爆炸");
        }
        System.out.println("电压是 "+recharge+"手机正在充电");
    }
}

package ink.yql.adapter;

public class PowerSupply {

    public int discharge(){
        return 220;
    }

}

package ink.yql.adapter;

public class PhoneAdapter  extends  Phone{
    private PowerSupply power;

    public PhoneAdapter(PowerSupply power) {
        this.power = power;
    }

    public int discharge(){
        int discharge = power.discharge();
        return discharge -210 -5 ;
    }
