“Since you have posted a question with multiple sub-parts, we will solve first three sub- parts for you. To get remaining sub-part solved please repost the complete question and mention the sub-parts to be solved.” A platform-neutral, object-oriented programming language is called Java (OOP). The scripting language used to produce dynamic web pages, JavaScript, should not be confused with it. Java is among the most used programming languages worldwide because of its dependability and simplicity. Java stores 2D arrays as arrays of arrays. Because to this, declaring 2D arrays is similar to declaring 1D array objects. To declare a 2D array, two sets of square brackets are placed after a data type definition.Source Code: import java.util.Scanner; public class TwoDArray { public static void main(String[] args) { Scanner input = new Scanner(System.in); int[][] arr = new int[3][3]; for (int i = 0; i < 3; i++) { for (int j = 0; j < 3; j++) { System.out.print("arr[" + i + "][" + j + "] = "); arr[i][j] = input.nextInt(); } } for (int i = 0; i < 3; i++) { for (int j = 0; j < 3; j++) { System.out.print(arr[i][j] + " "); } System.out.println(); } }}Output :

Passing Array as Argument

An array is a data structure that holds only fixed-size data and its contents are arranged in contiguous memory slots. The primary purpose of using an array is to store data items of the identical type together. An array can stockpile any one of the following types of data: int, float, char and so forth. The elements are stored from index 0, and the difference between the two indexes of the array is termed as an offset. The array has a fixed size. Once the size is defined during array declaration, it cannot be changed later.

Take arr as any integer array of any size.
Consider the following program specification: Write a program that will prompt the user for 10 integer values and stores them in an array. The values entered by the user only be between 0 and 100 and the program should validate these appropriately. The program should then: Display the average of the values Display the highest value in the array Display the lowest value in the array Discuss how the values should be validated.

Program: Using a multidimensional array, create a triangular-shaped array. You will ask the user how many lines they want to see and then create the array, fill it, and then print it. You will fill the array with one 1 in the first row, two 2’s in the second row, etc. This should work for any integer that the user enters. (Just because I am starting on 1 does not mean row 0 was skipped.) You must: use a loop to create the array shape. You must: use nested for loops to fill the array and to print the values back to the screen. Your program should print as shown below. Example Output: How many lines would you like in your triangle? >>>9 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5 6 6 6 6 6 6 7 7 7 7 7 7 7 8 8 8 8 8 8 8 8 9 9 9 9 9 9 9 9 9 If your code looks like the code below, it is not what I’m asking for.
