Can we call static method in non static method?
It is a method which belongs to the class and not to the object(instance).
A static method can access only static data.
It cannot access non-static data (instance variables).
A static method can call only other static methods and can not call a non-static method from it..
Can abstract class have methods?
Abstract classes are similar to interfaces. You cannot instantiate them, and they may contain a mix of methods declared with or without an implementation. However, with abstract classes, you can declare fields that are not static and final, and define public, protected, and private concrete methods.
Can abstract class have main method?
Yes, you can use the main method in abstract class. The main method is a static method so it is associated with Class, not with object/ instance. … In main method, you can not create an instance of the abstract class but you can instantiate other concrete class.
Can we have static method in abstract class?
Can an abstract class have static methods? Yes, abstract class can have Static Methods. The reason for this is Static methods do not work on the instance of the class, they are directly associated with the class itself.
Can we write a static modifier in an abstract class?
A Java class containing an abstract class must be declared as abstract class. An abstract method can only set a visibility modifier, one of public or protected. That is, an abstract method cannot add static or final modifier to the declaration.
Why would you make a method static?
Static method(s) are associated to the class in which they reside i.e. they can be called even without creating an instance of the class i.e ClassName. methodName(args). They are designed with aim to be shared among all Objects created from the same class. Static methods can not be overridden.
Can we override static method?
Can we Override static methods in java? We can declare static methods with the same signature in the subclass, but it is not considered overriding as there won’t be any run-time polymorphism. Hence the answer is ‘No’.
Why we Cannot override static method?
Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).
Why we Cannot use static and abstract?
An abstract class cannot have a static method because abstraction is done to achieve DYNAMIC BINDING while static methods are statically binded to their functionality. A static method means behavior not dependent on an instance variable, so no instance/object is required.
Can a static method be final?
Static methods belong to the class, not the instance. … Static methods with the same signature from the parent class are hidden when called from an instance of the subclass. However, you can’t override/hide final methods. You would think the error message would use the word hidden instead of overridden…
Can we override main method?
No, we cannot override main method of java because a static method cannot be overridden. The static method in java is associated with class whereas the non-static method is associated with an object.
Can abstract class have constructors?
Yes! Abstract classes can have constructors! Yes, when we define a class to be an Abstract Class it cannot be instantiated but that does not mean an Abstract class cannot have a constructor. Each abstract class must have a concrete subclass which will implement the abstract methods of that abstract class.
