Difference between initializing a class and instantiating an object?

Question

I tried searching for this question through the search engine but could find a topic that explained the difference between initializing a class and instantiating an object.<

Answer 1

Point originOne = new Point(23, 94); -- Example 1

Rectangle rectOne = new Rectangle(originOne, 100, 200); -- Example 2

1) Declaration: The code set in bold are all variable declarations that associate a variable name with an object type.

2) Instantiation: The new keyword is a Java operator that creates the object.

3) Initialization: The new operator is followed by a call to a constructor, which initializes the new object.
