What is Constructor in Java

Constructor is a special type of method which is used to initialize objects.
When an object is created then the compiler will automatically invoke the default constructor to allocate memory and assign default values (if not assigned) or assign declared values.
Every time a new object is created using “new” keyword then a constructor is called.
While declaring Constructor, the class name and constructor name should be the same.
Constructors do not have any return type.
