This paper presents a small extension to the Java language with dependent types and inheritable constructors. A dependent type is the most specific type of a given object. In essence it is already known in other languages such as Eiffel. There the definition was unfortunately flawed. Also ...
Subtypes of Java constructors In common parlance, you may also hear developers speak about other types of Java constructors: Copy constructors. Parameterized constructors. No-args constructors. Non-default constructors. However, technically all of these are subtypes of the 10 Java constructor types...
Constructor in Java Whenever we usenewkeyword to create an instance of a class, the constructor is invoked and the object of the class is returned. Since constructor can only return the object to class, it’s implicitly done by java runtime and we are not supposed to add a return type t...

Type[]getGenericParameterTypes() Returns an array of Type objects that represent the formal parameter types, in declaration order, of the executable represented by this object. intgetModifiers() Returns the Java language modifiers for the executable represented by this object. StringgetName() Returns...
Constructor overloading is a concept of having more than one constructor with different parameters list, in such a way so that each constructor performs a different task. For e.g.Vectorclass has 4 types of constructors. If you do not want to specify the initial capacity and capacity incremen...

4. Constructor Chaining withthis()andsuper() In Java, it is possible to call other constructors inside a constructor. It is just like method calling but without any reference variable (obviously, as the instance is NOT fully initialized as of now). ...
