This article introduces the relevant knowledge of "what are the calls of java methods?". In the operation of actual cases, many people will encounter this dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

There are mainly several kinds of method calls in JAVA: 1. Non-static methods are methods without static modification. Calls to non-static methods are called through an object, as shown below.

Object name. Method ()

Eg:

Public class InvokeMethod {public static void main (String [] args) {InvokeMethod in = new InvokeMethod (); in.t1 ();} public void T1 () {System.out.printfln ("T1");}}

two。 Calling a static method is a method decorated with static. The call to a static method is called through the class name, as shown below:

Class name. Method ()

Eg:

Public class InvokeMethod {public static void main (String [] args) {InvokeMethod.t2 ();} public static void T2 () {System.out.println ("static T2....");}}

3. The call between methods and methods is mainly about how to call other methods within one method. (1) calling other methods inside static methods if in this class, static methods can call static methods directly, not only in main methods, but also in custom static methods. If it is a non-static method in this class, it must be called through an object.

Public class InvokeMethod {public static void main (String [] args) {T2 ();} public static void T2 () {System.out.println ("static T2...");} public static void T1 () {/ / static method call non-static method calls / / InvokeMethod in = new InvokeMethod (); / / in.t2 (); T2 () System.out.println ("static T1");}}

If you are not in one class, static methods call static methods in other classes, and you must pass the

Class name. Static method ()

If a static method calls a non-static method of another class in a different class, you need to import the package in that class and call it by creating an object.

(2) Internal calls to non-static methods if in this class, non-static methods can directly call static methods and non-static methods. In different classes, when non-static methods call static methods of other classes, you need to import packages in this class, and you need to call them through class names. When non-static methods call non-static methods of other classes, you need to import packages in this class and call them by creating objects.
