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...

the Java platform differentiates constructors on the basis of the number of arguments in the list and their types. You cannot write two constructors that have the same number and type of arguments for the same class, because the platform would not be able to tell them...
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...
You must have understood the purpose of constructor overloading. Lets see how to overload a constructor with the help of following java program.

In this program, we have not defined a copy constructor. The compiler used the default copy constructor to copy the contents of one object of theWallclass to another. Also Read C++ Destructors C++ Constructor Overloading C++ Friend Function and Classes ...
programmar creates an object of classB(either via declaration or with a call tonew), the creation operation specifies arguments for aBconstructor. These arguments allow the C++ compiler to resolve overloading when multiple constructors exist. But where does the compiler obtain arguments for theA...
