java - 将对象变量放入扫描仪中

Question

我对java很陌生，所以任何输入或帮助将不胜感激。我正在尝试创建一个程序，要求用户为 Car 类提供一系列输入(例如名称、注册、颜色、行程数和里程表读数)。我创建了一个汽车类，创建了该类的一个名为 carSample 的对象，并在我的主方法中为其指定了相同的变量名称，在该方法中我使用扫描仪询问名称、注册等...

但是，这不起作用，我收到错误:

TestCar.java:8: error: ';' expected String carSample.name = input.nextLine();

这是我的代码:

public static void main(String[] args){

    Scanner input = new Scanner(System.in);

    System.out.print("Input name: ");

    String carSample.name = input.nextLine();

    System.out.print("Input registration: ");

    String carSample.registration = input.nextLine();

    System.out.print("Input colour: ");

    String carSample.colour = input.nextLine();

    System.out.print("Input trips: ");

    int carSample.numberOfTrips = input.nextInt();

    for (int i = 0; i < numberOfTrips; i++) {
        System.out.print("Odometer reading " + (i + 1) + ": ");
        int odometerReading = input.nextInt();
    }

    car carSample = new car(); // Creates object of class Car
}

class car {
    String name;
    String registration;
    String colour;
    int numberOfTrips;
    double odometerReading;
}

任何帮助将不胜感激，谢谢!

Answer 1

`import java.util.*;

class Test{
public static void main(String[] args){

    Scanner input = new Scanner(System.in);
        car carSample = new car(); // Creates object of class Car
    System.out.print("Input name: ");


    carSample.name = input.nextLine();

    System.out.print("Input registration: ");

     carSample.registration = input.nextLine();

    System.out.print("Input colour: ");

 carSample.colour = input.nextLine();

    System.out.print("Input trips: ");

 carSample.numberOfTrips = input.nextInt();

    for (int i = 0; i < carSample.numberOfTrips; i++) {
        System.out.print("Odometer reading " + (i + 1) + ": ");
        int odometerReading = input.nextInt();
    }


}

}
class car {
    String name;
    String registration;
    String colour;
    int numberOfTrips;
    double odometerReading;
}`

试试这个......这应该有效......
