  • If we remove the parameterized constructor from the above code then the program would run fine, because then compiler would insert the default constructor into your code. Constructor Chaining When A constructor calls another constructor of same class then this is called constructor chaining.
  • When programmer do not implement any constructor, non-parameterized constructor or parameterized constructor then Java compiler provide a special constructor called default constructor. These constructor doesn’t seems in your Java source code because the compiler insert it into your code during compilation, so, it is available in .class file.
  • If we remove the parameterized constructor from the above code then the program would run fine, because then compiler would insert the default constructor into your code. Constructor Chaining When A constructor calls another constructor of same class then this is called constructor chaining.
  • Constructors can be overloaded too i.e. defining different parameterized constructors will result in constructor overloading. Lets add a overloaded constructor in above class i.e. Lets add a overloaded constructor in above class i.e.
