Program Plan Intro
Three-dimensional array:
An array of array of arrays is called as three-dimensional array. It is a collection of two-dimensional arrays, and a two-dimensional array is an array of one-dimensional array.
Example:
Consider an example for three-dimensional array is as follows:
int [][][] a = new int[3][4[][5];
Here, “a” can hold maximum of 60 (3 * 4* 5) elements of type “int”.

Problem2: 2D Arrays
Define a 2D array using Java code that takes from a teacher the total number of rows and the
total number of columns. Then let the teacher fill the array by students IDs and courses marks
for each student. And print the following:
1- Print the array.
2- Print the marks that are less than 50 (mark < 50)
2D arrays (matrices/grids)
Write a program that takes 20 student objects and stores them in an array.
Each Student object should have a first name and a last name.
Sort the array by student’s last name. You can use any of the sorts you have.
Then put the names into a 2D array that has 5 rows and 4 columns.
Create 2 seating charts by printing the 2D array.
