What is the difference between static and dynamic loading Java?

What is dynamic loading Java?

Dynamic Class Loading allows the loading of java code that is not known about before a program starts. The Java model loads classes as needed and need not know the name of all classes in a collection before any one of its classes can be loaded and run. … You can create object at run time by dynamic class loading.

What is static and dynamic class loading?

Static Class Loading: Creating objects and instance using new keyword is known as static class loading. The retrieval of class definition and instantiation of the object is done at compile time. … Dynamic class loading is done when the name of the class is not known at compile time.

What is the difference between static and dynamic binding in Java?

Static binding uses Type information for binding while Dynamic binding uses Objects to resolve binding. Overloaded methods are resolved (deciding which method to be called when there are multiple methods with same name) using static binding while overridden methods using dynamic binding, i.e, at run time.

Is a class static or dynamic?

Can static methods be private?

Static methods can be public or private. The static keyword is placed right after the public/private modifier and right before the type of variables and methods in their declarations.

Can we 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).

What is the difference of static and dynamic?

In general, dynamic means energetic, capable of action and/or change, or forceful, while static means stationary or fixed. In computer terminology, dynamic usually means capable of action and/or change, while static means fixed.

Is Java dynamic or static?
