使用未知参数长度调用未知构造函数

import java.lang.reflect.Constructor;
import java.lang.reflect.InvocationTargetException;

public class Main {
    public static void main(String[] args) {
        try {
            // 获取类的构造函数
            Class<?> clazz = MyClass.class;
            Constructor<?> constructor = clazz.getConstructor(String.class, int.class);

            // 构造函数参数
            Object[] params = new Object[]{"example", 123};

            // 调用构造函数创建对象实例
            Object instance = constructor.newInstance(params);

            // 输出对象实例
            System.out.println(instance);
        } catch (NoSuchMethodException | IllegalAccessException | InstantiationException | InvocationTargetException e) {
            e.printStackTrace();
        }
    }
}
