这是我目前正在处理的基础课程的代码。我一直收到错误,但我不确定我做错了什么。任何帮助将不胜感激。谢谢!

package miles;

public class Miles {

    private int miles;
    private int gas;
    public static int mpg;

    public void setMiles(int miles) {

        this.miles = miles;

    }

    public void setGas(int gas){

        this.gas = gas;

    }


    public int getMpg(){
        mpg = miles/gas;
        return mpg;
    }


}
package miles;
import java.util.Scanner;

public class MilesDriver {


    public static void main(String [] args) {


        Miles gas =  new Miles();

        Scanner input = new Scanner(System.in);

        System.out.println("Enter Miles: ");
        int setGas = input.nextInt();

        System.out.println("Enter Gas: ");
        int setMiles = input.nextInt();

        System.out.printf("MPG:  %n%s%n",  gas.getMpg() );


    }
}

答案 0 :(得分:0)

您实际上忘了设置对象的值:

    System.out.println("Enter Miles: ");
    int setMiles = input.nextInt();
    gas.setMiles(setMiles);

    System.out.println("Enter Gas: ");
    int setGas = input.nextInt();
    gas.setGas(setGas);

尽量不要给变量命名与对象的方法同名。你会迷惑自己并陷入困境。
