Question 1: BMI (Body Mass Index) Calculator (use "if" "if-else") You are developing a program that calculates a person's BMI based on their weight (in kilograms) and height (in meters). Write a Java program that takes the weight and height as input and calculates the BMI using the formula: BMI = weight/ (height^2). The program should then categorize the BMI as follows: Underweight: BMI less than 18.5 Normal weight: BMI between 18.5 and 24.9 Overweight: BMI between 25 and 29.9 Obesity: BMI 30 or greater Display the BMI in the format of %.2f. Please check the usage of System.out.format. After showing the user the category, you ask the user a question "do you some tips according to your BMI?". If the user input yes/y/Y, you print the follow information accordingly: Underweight: "Please eat well and do more excises." Normal weight: "Congratulations, you are doing fairly well. Keep on going." Overweight: "Please watch out what you eat and do more excises!" Obesity: "Please contact our experts for professional help." If the user input anything else, you print the message "Nice to meet you too. Bye!" The output is shown as following (Here show imcomplete combinations of BMI and yes/Y/y and some cases of non yes/Y/y inputs.)
