我的java程序已编译，但赢得了'；跑不动

我的java程序可以编译，但在尝试运行它时不会返回任何内容。我正在做一个作业，在作业中我使用了多种方法，我不确定我是否对这些方法做了一些错误的事情，这些错误可能会影响程序的运行

如果（monstersHealth如我所见，主方法中没有方法调用，请尝试在主方法中调用静态方法，如下所示

public static void main(String[] args){

        int monstersHealth = 100;
        int monsterAttackpower = 0;
        String monstersName;
        int xp;
        int yourHealth = 0;
        int yourAttackpower = 0;
        int magicPower = 0;
        int magicPoints = 0;
        int statPoints = 20;
        createHero();
        createMonster();
        runCombat();
    }

您没有在main函数中调用任何方法，因此它只是创建您在main中声明的变量，并返回，而不提供任何输出

您需要在main函数中创建流

public static void main(String[] args){

    int monstersHealth = 100;
    int monsterAttackpower = 0;
    String monstersName;
    int xp;
    int yourHealth = 0;
    int yourAttackpower = 0;
    int magicPower = 0;
    int magicPoints = 0;
    int statPoints = 20;
    createHero();
    runCombat();
}

你没有调用任何方法，java不应该以这种方式使用！！
对于您的情况，在main方法中初始化变量是没有用的，您可以在main方法中调用函数（根据我的说法，如果您在构造函数中调用函数，而不是在main方法中调用函数，并将变量用作类的实例变量，那么您可以在不同的方法中使用这些函数）

JavaScript不是Java.Java！==javascriptin其主函数不调用任何方法当它不运行时意味着什么。有错误消息吗？有调试尝试吗？
