Question
- Write a Java application for a grade book using arrays:
- Create an array to store 20 test grades, random numbers between 0-100, inclusive.
- Print these 20 grades
- Calculate and print the average grade
- Calculate and print the highest and lowest grades
- Complete BMI arrays template BMI.java
- Use two int arrays to store n numbers from user input, called height[] and weight[].
- "The BMI is defined as the body mass divided by the square of the body height"
- Calculate BMIs and store values into a double array called bmi[].
- Write a method to print an array, use an enhanced for loop in the print method.
- Print the BMIs by invoking the print method.
- import java.util.Scanner;
public class BMI{
public static void main(String[] args){
Scanner key = new Scanner (System.in);
int num = // use Scanner object to get an integer
// declare an int array for height
int[] height = new int[num];
// declare an int array for weight below
...
// declare an array for BMI array
...
for ( ){ // iterate all array elements, calculate BMI values
...
...
}
}
}

- Problem Description - JAVA PROGRAMMING Use a Two-dimensional (3x3) array to solve the following problem: Write an application that inputs nine numbers, each of which is between 1 and 10, inclusive. Display the array after the user inputs each value. Rotate/flip the array by changing places. Make the rows columns and vice versa. You have to move the elements to their new locations. Remember to validate the input and display an error message if the user inputs invalid data. Documentation and the screenshot(s) of the results.

Radio buttons should allow the choice between First Class and Economy. The app should then assign a seat in the first-class section (seats 1–5) or the economy section (seats 6–10). Use a one-dimensional array of type bool to represent the seating chart of the plane. Initialize all the elements of the array to false to indicate that all the seats are empty. As each seat is assigned, set the corresponding element of the array to true to indicate that the seat is no longer available. Your app should never assign a seat that has already been assigned. When the economy section is full, your app should ask the person if it is acceptable to be placed in the first-class section (and vice versa). If yes, make the appropriate seat assignment. If no, display the message "Next flight leaves in 3 hours."arrow_forward
