A. In a hotel, each room has exactly 3-digit id and a positive price. Develop a class in java to represent class Room strictly as follows: 1. Define the class Room 2. Define price fields to be private and the id to be public. 3. Define the default constructor that sets an object with values id:1 and price:70.5 4. Define a setter method for price (Make sure to not accept negative price) 5. Define a getter method for price. 6. Define the toString method of the class such that it returns a string representing the room. e.ga ID: 412 Price: 80.25 B. Based on the Room class above complete the main method below public class TestProduct public static void main(String[] args) // 1. Create a Room objects r1 with the following values: id is 521 and price 100 1/ 2. Increment the price of r1 by 10. // 3. Change the id of ri to be 140. // 4. Use toString method to print ri id and price
