In Java, functions can be called using the following methods:<\/p>\n

    \n
  1. Calling a function directly: If the function is defined in the same class, you can call the function by using its name followed by the parameter list. For example:<\/li>\n<\/ol>\n
    public class MyClass {\r\n    public void myFunction() {\r\n        \/\/ \u51fd\u6570\u4f53\r\n    }\r\n\r\n    public static void main(String[] args) {\r\n        MyClass myObject = new MyClass();\r\n        myObject.myFunction(); \/\/ \u8c03\u7528myFunction\u51fd\u6570\r\n    }\r\n}\r\n<\/code><\/pre>\n
      \n
    1. To call a function using an object: If the function is defined in another class, you need to create an object of that class and then use the object name followed by the function name and parameter list to call the function. For example:<\/li>\n<\/ol>\n
      public class MyOtherClass {\r\n    public void myFunction() {\r\n        \/\/ \u51fd\u6570\u4f53\r\n    }\r\n}\r\n\r\npublic class MyClass {\r\n    public static void main(String[] args) {\r\n        MyOtherClass myOtherObject = new MyOtherClass();\r\n        myOtherObject.myFunction(); \/\/ \u8c03\u7528MyOtherClass\u7c7b\u4e2d\u7684myFunction\u51fd\u6570\r\n    }\r\n}\r\n<\/code><\/pre>\n
        \n
      1. To call a static function using the class name, you can simply use the class name followed by the function name and parameter list. For example:<\/li>\n<\/ol>\n
        public class MyOtherClass {\r\n    public static void myStaticFunction() {\r\n        \/\/ \u51fd\u6570\u4f53\r\n    }\r\n}\r\n\r\npublic class MyClass {\r\n    public static void main(String[] args) {\r\n        MyOtherClass.myStaticFunction(); \/\/ \u8c03\u7528MyOtherClass\u7c7b\u4e2d\u7684\u9759\u6001\u51fd\u6570\r\n    }\r\n}\r\n<\/code><\/pre>\n
        It is important to note that when calling a function, the correct parameter list needs to be passed, with the parameters’ types and order matching the function’s definition. If the function returns a value, you can assign the return value to a variable or use it directly.<\/p>\n","protected":false},"excerpt":{"rendered":"
