In programming languages like Swift or Objective-C, the keyword override is used to override instance methods in subclasses.
Static methods (declared with static) do not support overriding because they belong to the class itself, not to an instance, and are resolved at compile time.
In Swift, for methods that can be overridden at the class level, the keyword class is used instead of static. These methods are called "class methods" and can be overridden in subclasses using override.
Example in Swift:
class Parent {
class func greet() {
print("Hello from Parent")
}
static func staticGreet() {
print("Static Hello from Parent")
}
}
class Child: Parent {
override class func greet() {
print("Hello from Child")
}
// override static func staticGreet() { } // Compilation error
}
Parent.greet() // Hello from Parent
Child.greet() // Hello from Child
Parent.staticGreet() // Static Hello from Parent
Child.staticGreet() // Static Hello from Parent
Summary: the keyword override cannot be applied to static methods (static), but can be applied to methods declared with class, which support overriding.
