给定一个接受方法作为输入的方法，获取它的类和方法名

import java.lang.reflect.Method;

public class MethodUtil {
    public static void getMethodName(Object obj, String methodName) throws NoSuchMethodException {
        Class<?> clazz = obj.getClass();
        Method method = clazz.getMethod(methodName);
        String className = clazz.getName();
        String methodName = method.getName();
        
        System.out.println("Class Name: " + className);
        System.out.println("Method Name: " + methodName);
    }
}
