Suppose the item price before update was 10 SAR. (2 Marks) Q2) Create a class World with fields continents and countries and implement the concept of constructor overloading. Declare 3 constructors (Empty constructor, Partial argument constructor, Full argument constructor). (2 Marks) Q3) Create a class Shape that defines a variable named window of type Rectangle, and then create a rectangle object and assign it to the variable window. The rectangle constructor has two int parameters. (2 Marks) Q1) Create a class Restaurant having fields Item_name Item_code, and Item_Price.
