    Default Re: Static and non-static method

    A static method is a method of the class while a non-static method is a method of an instance of the class. So you can call a static method by using the class's name and calling the method off of this name using Java's standard dot notation:


    where here we call System's static method, exit(), on the System class.

    While instance methods must be called on objects of the class. i.e.,
    Random rand = new Random(); // create an instance
    int randomInt = rand.nextInt(100); // call a method on this instance

    To understand this you have to know what instances or objects are. Have you read up on this? Do you know where the Java tutorials are located as this has all be well discussed there and on other sites that can easily be found by Google.
