Just re-watched. Wow...you're an incredible teacher. Why can't everyone just say what this is like you did. It's a way for the JRE to distinguish between a class property and a parameter in a constructor or mutator that is being used to initialize or change it. You are a Java guru. Thx again.

Moreover, we use the this(); in constructors in Java to make all constructors call only one constructor so that we don't have to repeat our logic. There are tutorials I have created on constructors and overloaded constructors. I am not sure if you have watched those. Also, there is an 8-part tutorial on Object Oriented Programming example.

The usage of this keyword is done only inside a constructor which has the same names for local parameters and class non-static properties. The statements above are the three unique calls from main or any other caller to the constructor. You can call constructor with hardcoded values or through parameter. Parameter name of the caller makes no difference it is only on the called side, which is the constructor where we will be forced to use the this keyword if the parameter and property name match
