Create a java program that initialize a two dimensional array with the continuous assessment marks used to determine the semester mark for PRG510S exam qualification, The system should also create an array of student names in correspondence to the marks (Note: the appropriate weights of each individual assessment are given under corresponding headings and both the marks and student names are read from the user input).

Write a java program that accepts given n number of marks for a PRG510S test, and stores them into an array named marks. After all marks have been entered your program should accomplish the following:
[n - to be provided by user input]
a) Find and display the highest mark
b) Find and display the lowest mark
c) Compute and display the average mark
(Above tasks (a, b, and c should be accomplished using only one loop)
Sample Run1
Enter numbers of marks: 10
Enter 10 marks: 55 60 89 75 25 77 92 15 68 40
Output1: Highest Mark = 92%
Lowest Mark = 15%
Average = 58%
Write a java program that specifies three parallel one dimensional arrays name length, width, and area. Each array should be capable of holding a number elements provided by user input. Using a for loop input values for length and width arrays. The entries in the area arrays should be the corresponding values in the length and width arrays (thus, area[i] = length [i]* width [i]) after data has been entered display the following output:
Length Width Area
-------- -------- -------
25 2.6 65.00
18.2 4.9 89.18
Sample Run1
Enter the array size: 5
Enter the Length and Width for Rectangle 1: 25 2.6
Enter the Length and Width for Rectangle 2: 18 4.9
Enter the Length and Width for Rectangle 3: 100 3.27
Enter the Length and Width for Rectangle 4: 1.84 7.4
Enter the Length and Width for Rectangle 5: 56 9.5
