Java应用程序不显示输出 [英] Java application doesn't display output

问题描述

这是我更新的代码：

package car1;

public class Main {

public class Main {

public static void main（String [] args）{

public static void main(String[] args) {

class HondaCivic implements car1 {

class HondaCivic implements car1 {

int speed = 0;
int rpm = 0;
int gear = 1;

public void speedUp(int Increment) {
    speed = speed + Increment;}

public void applyBrakes(int Decrement) {
    speed = speed - Decrement;}

public void changeRpm(int NewValue) {
    rpm = NewValue;}

public void changeGear(int NewValue) {
    gear = NewValue;}

public void printStates() {
    System.out.println("speed:"+speed+" rpm:"+rpm+" gear:"+gear);}

}

class CarDemo{
public void main(String[] args) {
    // Two different Cars
    HondaCivic car1 = new HondaCivic();
    HondaCivic car2 = new HondaCivic();
    // Methods for cars
    car1.speedUp(30);
    car1.changeGear(3);
    car1.changeRpm(3000);
    car1.applyBrakes(15);
    car1.printStates();

    car2.speedUp(30);
    car2.changeGear(3);
    car2.changeRpm(2000);
    car2.applyBrakes(15);
    car2.speedUp(5);
    car2.changeGear(1);
    car2.printStates();
}

}
}
}

} } }

应用程序将不显示输出。我不知道该怎么办。任何建议？

The application will not display the output. I have no idea what to do. Any advice?

推荐答案

Java与大多数编程语言一样，区分大小写。 类与 class 不同。

Java, like most programming languages, is case-sensitive. Class is not the same thing as class.
