Static Binding and Dynamic Binding in Java

Static Binding and Dynamic Binding in Java

Binding is the way toward associating the strategy call to the technique body or deciding the kind of the item.

In Java, there are two sorts of binding, static binding and dynamic binding. I have clarified them individually in this instructional exercise.

Static Binding in Java

1. At the point when sort of the article is controlled by the compiler at the incorporate time, it is called static binding or early binding.
2. We can likewise say that in static binding, the strategy call is associated with the technique body at an incorporate time.
3. Static binding happens when there is any private, last or static strategy in the class.

Let’s take one guide to comprehend static binding in java.

class Demo
{
 void show()
 {
  System.out.println("show");
 }
 
 public static void main(String...s)
 {
  Demo d=new Demo();
  d.show();
 }
}

Output

Show

As there are no superseded strategies so clearly every one of the techniques will be gotten to by object of neighbourhood class (object of Demo).

Likewise, the sort of the article is dictated by the compiler at the aggregate time in this manner static binding happens in the above model.

Dynamic Binding in Java

1. At the point when kind of the item is dictated by the compiler at run time, it is called as dynamic binding or late binding. We can likewise say that, in dynamic binding, the technique call is associated with the strategy body at run time.
2. The reference id of an inferred class object is put away in a reference variable of the base class. We can just access the superseded techniques, individual strategies and factors of the inferred class can’t be gotten to.
3. Dynamic binding happens when there are abrogated strategies or technique superseding.
4. Dynamic binding is utilized to accomplish reflection. We will find out about deliberation in the next instructional exercise.

Let’s take one guide to comprehend dynamic binding in java.

class Base
{
 
 void show()
 {
  System.out.println("Base");
 }
}
 
class Child extends Base
{
 void show()
 {
  System.out.println("Child");
 }
 
 public static void main(String...s)
 {
  Base b=new Child();
  b.show();
 }
}

output

Child

As should be obvious in the above model we are putting away the reference id of Child class into the reference variable of Base class.

At the point when I have called appear() technique, the strategy for Child class is called and the Output is “Child”.

On the off chance that Child class contains techniques other, at that point appear() at that point they can’t be gotten to utilizing variable b.

For getting to them we need to either typecast variable b or make another variable of Child class.

I trust that subsequent to peruse this instructional exercise the idea of static binding and dynamic binding in java will be clear in your brain.

I have likewise shared a video instructional exercise that will assist you with understanding these ideas effectively. In the event that you have any questions
