为什么`invokespecial`用于在java中调用`<init>`方法？

Question

Why is invokespecial used to invoke <init> method in java?

I read at multiple places but could not understand the perfect reason?

Any help would be appreciated.

Answer 1

From here :

The main use of invokespecial is to invoke an object's instance initialization method, <init> , during the construction phase for a new object.

Also from here :

In other words, invokespecial is used to call methods without concern for dynamic binding, in order to invoke the particular class' version of a method.

Second quotation is the most applicable to your question cause we know that calling constructor ( <init> ) method has always static binding.
