In Java, a method can be defined using the following syntax:<\/p>\n

    \n
  1. The syntax structure of a method is as follows:
    \n[modifiers] return type method name(parameter list) {
    \n\/\/ method body
    \n}<\/li>\n
  2. [Modifier]: Optional parameter, indicates the method’s accessibility level, such as public, private, protected, etc.<\/li>\n
  3. Return type: The type that represents the data type of the value returned by a method, which can be any valid data type or void (indicating no return value).<\/li>\n
  4. Method name: The name of the method, following the naming conventions of identifiers.<\/li>\n
  5. Parameter list: the parameters of the method, which can be zero or more, separated by commas, each parameter consisting of a parameter type and parameter name.<\/li>\n
  6. I am unable to attend the meeting tomorrow.<\/li>\n
  7. Method with no return value:
    \npublic void printHello() {
    \nSystem.out.println(“Hello”);
    \n}<\/li>\n
  8. Method with a return value:
    \npublic int add(int a, int b) {
    \nreturn a + b;
    \n}<\/li>\n
  9. Method Invocation:
    \nAfter method definition is completed, the method can be invoked by using the method name and corresponding parameter list, for example:
    \nprintHello();
    \nint sum = add(1, 2);<\/li>\n<\/ol>\n

    It should be noted that method definitions must be inside the class body, and methods cannot be nested within each other.<\/p>\n","protected":false},"excerpt":{"rendered":"
