Method:
A method is a block of code that performs a specific task. It is a collection of instructions grouped together to perform a particular operation. Methods can be used to perform actions, return values, or modify data.

Static and Non-static Methods:
Static Method: A method declared with the static keyword, which belongs to the class and can be called without an object.

Non-static Method: A method that does not have the static keyword and requires an object of the class to be invoked.

Key Points:
Static methods are associated with the class and do not require an instance to be called.
They can only access static variables and other static methods.

public static void myStaticMethod() {
    // code
}

Non-static methods are associated with objects (instances) and require an object to be called.
They can access both instance variables and static variables.

public void myNonStaticMethod() {
    // code
}

Example Programme:

public class Theatre {

    static String owner = "Sethu"; //class specific variable
    int ticket_fare;   //int       //non-static 
    float show_time;   //float 
    String movie_name; //String
    boolean on_screen; //boolean

//Method Definition
    public static void open_theatre() {
        System.out.println("Open Counters"); 
        System.out.println("Clean All Areas");
    }

//Non-static method definition
    public void cast_movie() { 
        System.out.println("Watching Movie "  +movie_name);
    }

public static void main(String[] args) {

    Theatre screen1 = new Theatre(); 
    Theatre screen2 = new Theatre(); 
    Theatre screen3 = new Theatre(); 

    screen1.movie_name = "Leo";
    screen2.movie_name = "Vidaamuyarchi";
    screen3.movie_name = "VDS Part 2";
//    screen1.show_time = 11.30f; 
//    ticket_fare = 120; 

    Theatre.open_theatre(); //Method Calling Statement or Static method
    screen1.cast_movie();   //Object - non-static 
    screen2.cast_movie();
    screen3.cast_movie();

    }
}
