Write a Java class called PyramidVolume that reads from the user 2 integers represent
area of the base (B) and the height of a pyramid (h).
Then calculates and prints the volume of this pyramid (rounded to 1 decimal place)
according to the following formula:
volume = (1/3) h B
Note:
If the user enters any non-positive value (i.e. less than or equal to zero), an error message
should be displayed and nothing should be calculated.

The Body Mass Index – BMI is a parameter used to measure the health status of an individual. Various BMI values depicts how healthy or otherwise a person is. Mathematically BMI = WEIGHT/ HIEGHT * HEIGHT
Write a java program using either JOptionPane or Scanner to collect the following values of an individual:
1.a. Namea
b. Weight
c. Height
2. Compute the BMI of that individual
3. Make the following decisions if:
a. BMI < 18.5 is under weight
b. BMI >=18.5 but <25 considerably healthy
c. BMI >=25 but <30 overweight
d. BMI >= 30 but <40 Obesity
e. BMI >= 40 Morbid Obesity
4. Display the results of the individual 5. Explain your answer

In this case, you are given a int[] rights, indicating the privilege level of each user to use some system resource. You are also given a int minPermission, which is the minimum permission a user must have to use this resource. You are to return a String indicating which users can and cannot access this resource. Each character in the return value corresponds to the element of users with the same index. 'A' indicates the user is allowed access, while 'D' indicates the user is denied access. Constraints users will contain between 0 and 50 elements, inclusive. Each element of users will be between 0 and 100, inclusive. minPermission will be between 0 and 100, inclusive. Examples a) {0,1,2,3,4,5} 2 Returns: "DDAAAA" Here, the first two users don't have sufficient privileges, but the remainder do. b) {5,3,2,10,0} 20 Returns: "DDDDD"…arrow_forward

- Javaarrow_forwardPythonarrow_forwardplease use java to answer the following question This task is required to create Craps, which is a popular dice game played in casinos. You are supposed to write a program to play a variation of the game, as follows: • Roll two dice. (Each roll should produce two random numbers between 1 to 6) • Each die has six faces representing values 1, 2, …, and 6, respectively. • Check the sum of the two dice. If the sum is 2, 3, or 12 (your program should display craps), you lose the game. • If the sum of the two dice is 7 or 11 (your program should display naturals), you win the game. • If the sum of two dice is any value (i.e., 4, 5, 6, 8, 9, or 10), your program should establish a point in the game (meaning store that sum). Continue to roll the dice until the sum is either a 7 or the same point value which was established. If rolled sum is 7, you lose the game. Otherwise, if the rolled sum is equal to established point you win.arrow_forward
