如何从基类中获取派生类名？

public class BaseClass {
    public void getDerivedClassName() {
        String className = this.getClass().getSimpleName();
        System.out.println("Derived class name: " + className);
    }
}

public class DerivedClass extends BaseClass {
    // ...
}

// 使用示例
DerivedClass obj = new DerivedClass();
obj.getDerivedClassName();

class BaseClass:
    def get_derived_class_name(self):
        class_name = type(self).__name__
        print("Derived class name:", class_name)

class DerivedClass(BaseClass):
    pass

# 使用示例
obj = DerivedClass()
obj.get_derived_class_name()
