Can we override static methods of a class?

Can we override static methods of a class?

No, we cannot override static methods because method overriding is based on dynamic binding at runtime and the static methods are bonded using static binding at compile time. ... If we call a static method by using the child class object, the static method of the child class will be called.

Can we override private static method?

No, we cannot override private or static methods in Java. Private methods in Java are not visible to any other class which limits their scope to the class in which they are declared.

Can static methods be inherited?

Static methods in Java are inherited, but can not be overridden. If you declare the same method in a subclass, you hide the superclass method instead of overriding it. Static methods are not polymorphic.

What is String [] args?

String[] args means an array of sequence of characters (Strings) that are passed to the "main" function. This happens when a program is executed. Example when you execute a Java program via the command line: java MyProgram This is just a test. Therefore, the array will store: ["This", "is", "just", "a", "test"]

What happens if I remove static from main method?

If the main method won't be static, JVM would not be able to call it because there is no object of the class is present. Let's see what happens when we remove static from java main method.

Can we override constructor?

It is never possible. Constructor Overriding is never possible in Java. This is because, Constructor looks like a method but name should be as class name and no return value.

How can I call non static method from static method?

The only way to call a non-static method from a static method is to have an instance of the class containing the non-static method. By definition, a non-static method is one that is called ON an instance of some class, whereas a static method belongs to the class itself.

Can static methods be overloaded?

Static methods in Java can be overloaded just as 'instance methods'. So it is possible to have two or more static methods having the same name, but the parameters are different in types or number.

Can you call non-static method from a static?

Non static methods will be executed or called by using object so whenever we want to call a non static method from static method we need to create an instance and call that method. If we are calling non static method directly from a static method without creating object then compiler throws an error.

Can We override the overloaded method?

Yes you can override the overloaded method. Overloading is when you define two methods with same name, in the same class, distinguished by their signatures. Overriding is when you redefine a method that has already been defined in a parent class(using the exact same signature) Overload is resolved at compile time.
