public class dd {
    public static void main(String[] args) {
        Car car=new Car("品牌","型号","马力");
        car.display();
    }
}
class Car{
    String brand;
    String version;
    String horsePower;
    public Car(String brand, String version, String horsePower) {
        super();
        this.brand = brand;
        this.version = version;
        this.horsePower = horsePower;
    }
    public String getBrand() {
        return brand;
    }
    public void setBrand(String brand) {
        this.brand = brand;
    }
    public String getVersion() {
        return version;
    }
    public void setVersion(String version) {
        this.version = version;
    }
    public String getHorsePower() {
        return horsePower;
    }
    public void setHorsePower(String horsePower) {
        this.horsePower = horsePower;
    }
    public void display() {
        System.out.println(brand+" "+version+" "+horsePower);
    }
}
