Use java code
Body Mass Index (BMI) is a measure of health on weight. It can
be calculated by taking your weight in kilograms and dividing by
the square of your height in meters.
The interpretation of BMI for people 16 years or older is as
follows:
BMI
below 16
16-18
19-24
25-29
30-35
above 35
Interpretation
seriously underweight
underweight
normal weight
overweight
seriously overweight
gravely overweight
Write a Java program that prompts the user to enter a weight in
kilograms and height in meter and display the BMI. Use nested if-
else statements to solve this exercise.
Here is a sample run:
Enter weight in kilograms: 66.22
Enter height in meters: 1.788
Your BMI is 20.71353142
You are normal weight
Write a Java regular expression for each of the following: a. Phone numbers, such as (609) 555-1234 b. Social Security numbers, such as 123-45-6789 c. Dates, such as December 31, 1999
Write a complete Java program that performs the following tasks:
1. Ask the user to enter the last two digits of his/her student ID.

second digits in integer variables named digitl and digit2
3. Find and print the following:
Note:
•
The product of digit] and digit2.
The sum of digit1 and digit2
•
The average of digit1 and digit2

- Use Java ⮚ Roman numerals are represented by seven different symbols: I, V, X, L, C, D and M. ⮚ Symbol Value I 1 V 5 X 10 L 50 C 100 D 500 M 1000.⮚ For example, 2 is written as II in Roman numeral, just two ones added together. 12 is written as XII, which is simply X + II. The number 27 is written as XXVII, which is XX + V + II. ⮚ Roman numerals are usually written largest to smallest from left to right. However, the numeral for four is not IIII. Instead, the number four is written as IV. Because the one is before the five we subtract it making four. The same principle applies to the number nine, which is written as IX. There are six instances where subtraction is used: I can be placed before V (5) and X (10) to make 4 and 9. X can be placed before L (50) and C (100) to make 40 and 90. C can be placed before D (500) and M (1000) to make 400 and 900. ⮚ Given a roman numeral, convert it to an integerarrow_forwardQuestion 3: Write a Java program that takes two numbers from user as input and display the sum (addition), multiply, subtract, divide and remainder of two numbers.
