We all know that constructors are nothing but methods in java. But, as all the methods are either static or non-static , Then, what is the type-access modifier for the constructor?

Constructors in Java are not classified as static or non-static methods. They are a special type of block that initializes objects and have no explicit type-access modifier classification. While they behave like instance methods (they run on object creation), they are not technically methods and don't fit into the static/non-static binary.
