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
    ...
    ...
    }
    
    }
    }
