To define an interface for external system calls in Java, you can follow these steps:<\/p>\n

    \n
  1. The file is named MyInterface.java.<\/li>\n
  2. In this class, methods are defined using interfaces, where the method declaration only includes the method name, parameter list, and return type, without the method body. For example:<\/li>\n<\/ol>\n
    public<\/span> interface<\/span> MyInterface<\/span> {\r\n    void<\/span> myMethod<\/span>()<\/span>;\r\n    int<\/span> add<\/span>(int<\/span> a, int<\/span> b)<\/span>;\r\n}\r\n<\/code><\/pre>\n
      \n
    1. The file named MyClass.java<\/li>\n<\/ol>\n
      public<\/span> class<\/span> MyClass<\/span> implements<\/span> MyInterface<\/span> {\r\n    @Override<\/span>\r\n    public<\/span> void<\/span> myMethod<\/span>()<\/span> {\r\n        \/\/ \u5b9e\u73b0\u63a5\u53e3\u4e2d\u7684\u65b9\u6cd5\u903b\u8f91<\/span>\r\n    }\r\n    \r\n    @Override<\/span>\r\n    public<\/span> int<\/span> add<\/span>(int<\/span> a, int<\/span> b)<\/span> {\r\n        \/\/ \u5b9e\u73b0\u63a5\u53e3\u4e2d\u7684\u65b9\u6cd5\u903b\u8f91<\/span>\r\n        return<\/span> a + b;\r\n    }\r\n}\r\n<\/code><\/pre>\n
        \n
      1. In external systems, the methods in the interface can be invoked in the following ways:<\/li>\n<\/ol>\n
        MyInterface<\/span> myObject<\/span> =<\/span> new<\/span> MyClass<\/span>();\r\nmyObject.myMethod();\r\nint<\/span> result<\/span> =<\/span> myObject.add(2<\/span>, 3<\/span>);\r\n<\/code><\/pre>\n
        This way, the defined interface methods can be called in external systems.<\/p>\n","protected":false},"excerpt":{"rendered":"
