According to the Java language specification, there are 10 different constructor types in Java:Default constructor. Explicit constructors. Canonical constructors. Superclass constructors. Anonymous constructors. Inner class constructors. Enum constructors. Generic constructors. Private constructors. ...
we also look at the types of constructors in java. We also talked about default constructors in java and how constructors are different from methods in java.
Overloading constructors can provide flexibility, but it can also lead to confusion if not done carefully. If two constructors have the same number of parameters of different types, Java may not know which one to use. Solution: To avoid this, make sure each overloaded constructor has a dist...

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...
