Classes: Methods

A method is a function defined in a class.

class Counter {
    public function increment(): void {
        // ...
    }
}

Method Calls

Refer to Expressions: Object Operations - Method Calls for more information.

Method Visibility

A method can be declared as public, protected, or private.

class Counter {
    public function increment(): void {
        // ...
    }

    protected function decrement(): void {
        // ...
    }

    private function reset(): void {
        // ...
    }
}

Final Methods

A method can be declared as final, which means that it cannot be overridden in a child class.

class Counter {
    final public function increment(): void {
        // ...
    }
}

Static methods

A static method is a method that can be called without creating an instance of the class.

class Counter {
    public static function increment(): void {
        // ...
    }
}

To call a static method, use :: operator.

function main(): void {
    Counter::increment();
}
