if括号里填入让电量减10，并输出剩余电量的代码

Question

import java.util.Scanner;
class Battery{
int electricityAmount;
Battery(int amount){
electricityAmount=amount;
}
}
class Radio{
void openRadio(Battery battery){
battery.electricityAmount=battery.electricityAmount-10;
}
}
class Nanfu{
public static void main(String args[]){
Battery nanfu = new Battery(100);
System.out.println("南孚电池的电量为："+nanfu.electricityAmount);
Radio radio=new Radio();
System.out.println("收音机开始使用南孚电池");
radio.openRadio(nanfu);
System.out.println("目前南孚电池的电量是："+nanfu.electricityAmount);
System.out.println("继续使用收音机输入1，不使用请输入2");
@SuppressWarnings("resource")
Scanner reader = new Scanner(System.in);
int x=reader.nextInt();
if(x==1)
{

 }
 else
 {
     System.out.println("感谢使用收音机!");
 }
 }

}

Answer 1

if(x==1)
{
nanfu.electricityAmount -= 10;
System.out.println("目前南孚电池的电量是："+nanfu.electricityAmount);
}
