当我尝试运行它时，我的java程序编译但不返回任何内容。我正在进行一项任务，我正在使用多种方法，而且我不确定我是否对可能对程序完全没有运行产生影响的方法做错了。

正如我所看到的，在main方法中没有方法调用尝试在main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();
}

您没有调用main函数中的任何方法。因此，它只是创建你在main中声明的变量并返回而不给出任何输出。
您需要在主函数
中创建流程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();
}

呀，你没有调用任何方法，并且不应该以这种方式使用java！ 对于你的情况，没有使用在main方法中初始化变量你可以在main方法中调用函数（如果你在构造函数中调用函数而不是在main方法中调用函数而使用变量为类的实例变量，所以你可以在不同的方法中使用它们。）
public CombatCalculatorExpansion1{
createHero();
createMonster();
runCombat();
}
