如何调用反射得到的闭包函数？

import java.lang.reflect.Method;

public class ReflectionExample {
    public static void main(String[] args) throws Exception {
        // 获取闭包函数的引用
        Method closureMethod = MyClass.class.getDeclaredMethod("closure");

        // 设置闭包函数的可访问性
        closureMethod.setAccessible(true);

        // 调用闭包函数
        closureMethod.invoke(null);
    }

    private static class MyClass {
        private static void closure() {
            System.out.println("This is a closure function.");
        }
    }
}
