- I learnt something new today and will be sharing it w everyone.
- We might have seen general uses of
thiskeyword to set the field values of object that is being called, but today we're about to see something interesting, the usage ofthiskeyword to call a constructor within another constructor. - This is called
explicit constructor invocation - In this example, the constructor with no arguments calls the constructor with four arguments and thereby setting those
fieldswith the given values.
- Note: This explicit invocation must be done the first line in the respective constructor body.
