This question is from the book OCP Java se 11 part 1
Exercise 4.7
Ques 4

Add an instance variable of type Bird in Bird. Initialize this variable
on the same line using "new Bird()" syntax. Instantiate a Bird object
in TestClass's main and execute it. Observe the output.


Here I am not able to understand what is the meaning of initialize the variables and the meaning of instantiate a Bird Object. Can you tell me the solution for this one

Please go through section 1.3 Declaration and Definition, which explains the meaning of initialization of a variable and section 4.1 Declare and instantiate Java objects, which explains instantiation.
