NameError: name 'overload' is not defined

override与overload-UML统一建模语言

override与overload 覆盖（override）在子类中增加或重新定义所继承的属性或方法。 public class A｛ String name; public String getValue(){ return “Value is:” + name; } ｝ public class B extends A { String address; public String getValue () { return “Value is:” + address; } }

NameError: name 'overload' is not defined是Python中的一个错误提示，意思是你在代码中使用了一个未定义的函数或变量overload。这通常是因为你没有正确导入需要使用的模块或库，或者是因为你没有在代码中定义这个函数或变量。要解决这个问题，你需要检查你的代码，确保你正确导入了需要使用的模块或库，并且在代码中定义了需要使用的函数或变量。
