How can I access value of ID to find the average?
问题
我有一个静态方法Das，它会接受两个类型为Car的对象，并返回id的平均值。我在访问id以找到平均值时遇到了困难。任何帮助将不胜感激。这是我的代码public class Car {private int id;private String name;public Car(int id, String name){this.id = id;this.name = name;}public static int Das( Car C1 , Car C2) {{return (C1.id + C2.id)/2 ;}// getter and setterTest.javapublic class Test {public static void main(String[] args) {Car car1 = new Car(1,"A");Car car2 = new Car(2,"V");double A= Das(car1,car2);System.out.println(A);}}
英文:
I have static method Das which will take 2 objects of type Car and return average value of id. I have difficulty accessing id to find the average. Any help will be appreciated
Here is my code
public class Car {private int id;private String name;public Car(int id, String name){this.id = id;this.name = name;}public static int Das( Car C1 , Car C2) {{return (C1.id + C2.id)/2 ;}// getter and setter
Test.java
public class Test {public static void main(String[] args) {Car car1 = new Car(1,"A");Car car2 = new Car(2,"V");double A= Das(car1,car2);System.out.println(A);}}</details># 答案1**得分**: 1以下是您要的翻译部分：对于返回 `int` 类型且会丢失小数部分的情况，可以按以下方式进行：```javapublic static int findAveCustomerId(Customer C1, Customer C2) {return (C1.id + C2.id) / 2;}
对于返回 double 类型且不会丢失小数部分的情况：
public static double findAveCustomerId(Customer C1, Customer C2) {return (C1.id + C2.id) / 2.0; // 注意小数点}
英文:
For an int return where you will lose fractions, do it as follows.
public static int findAveCustomerId(Customer C1 , Customer C2) {return (C1.id + C2.id)/2;}
For a double return where you won't lose fractions
public static double findAveCustomerId(Customer C1 , Customer C2) {return (C1.id + C2.id)/2.; // notice the decimal point.}</details>
