java - Why can't constructors be final, static, or abstract?

Question

Why can't constructors be final, static, or abstract in Java?

For instance, can you explain to me why this is not valid?

public class K {

    abstract public K() {
        // ...
    }
}

When you set a method as final it means: "I don't want any class override it." But according to the Java Language Specification:

JLS 8.8 - "Constructor declarations are not members. They are never inherited and therefore are not subject to hiding or overriding."

When you set a method as abstract it means: "This method doesn't have a body and it should be implemented in a child class." But the constructor is called implicitly when the new keyword is used so it can't lack a body.

When you set a method as static it means: "This method belongs to the class, not a particular object." But the constructor is implicitly called to initialize an object, so there is no purpose in having a static constructor.
