Core Java Programming Course- Two-dimensional (2D) Array Exercise

The video tutorial explains how to create a 2D array in a programming language, specifically to store multiplication tables for numbers two to six. It covers declaring a blank 2D array, using nested loops to populate it, adjusting indices for correct value assignment, and printing the array in a formatted manner. The tutorial concludes with a recap of the steps and the program's output.

What is the purpose of creating a 2D array in this program?

• To perform addition of two numbers

• To sort a list of numbers

• To generate tables of numbers from two to six

• To store a list of names

How many rows are there in the 2D array?

• 3 rows

• 4 rows

• 5 rows

• 6 rows

What is the role of the outer for loop in the program?

• To print the array

• To perform multiplication

• To iterate over the columns

• To iterate over the rows

What does the inner for loop do in the context of this program?

• It iterates over the columns

• It iterates over the rows

• It performs addition

• It sorts the array

Why do we subtract two from the row index when assigning values?

• To perform subtraction

• To decrease the column number

• To increase the row number

• To adjust for the array starting index

What is the difference between print and println in this context?

• Print moves the cursor to the next line

• Println waits for user input

• Println moves the cursor to the next line

• Print waits for user input

How are the values of the 2D array printed in one line?

• By using println

• By using print with a space

• By using a loop

• By using a comma
