ConstructorParameters An annotation on a constructor that shows how the parameters of that constructor correspond to the constructed object's getter methods. For example: public class MemoryUsage { // standard JavaBean conventions with getters @ConstructorParameters({"init", "used", "committed", "...
Advantage It simulates named optional parameters which is easily used to client API. Detect the invariant failure(validation error of field) as soon as the invalid parameters are passed, instead of waiting for build to be invoked. The builder can fill in some fields automatically such as ...

Two Constructor objects are the same if they were declared by the same class and have the same formal parameter types. Overrides: equals in class Object Parameters: obj - the reference object with which to compare. Returns: true if this object is the same as the obj argument; false ...
3.1. Default Constructor If we do not provide any constructor in the class, JVM provides a default constructor to the class during compile time. In the default constructor, the name of the constructor MUST match the class name, and it should not have any parameters. ...
constructors or static factories and switch to a builder when the class evolves to the point where the number of parameters gets out of hand, the obsolete constructors or static factories will stick out like a sore thumb. Therefore, it’s often better to start with a builder in the first...

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...
