Workbook 6.14

From Java Bootcamp Resources -> Module 1 -> 6. Arrays, open Workbook 6.14.

Random Numbers!

In this workbook, you'll generate a thousand random numbers and store them in a 2D array.

Task 1

Write a function that returns a random number between 1 and 100.

/**
 * Function name: randomNumber.
 *
 * @return randomNumber (int)
 *
 * Inside the function:
 *    1. return a random number between 1 and 100.
 */

Task 2

Write a function that prints any 2D array in this format.

• Each row takes up one line.

• There's a space between each value in the row.

Hint: use a nested loop.

/**
 * Function name: print2DArray
 * @param array ( int[][] )
 *
 * Inside the function:
 *  1. print the array such that:
 *       - Each row takes up one line.
 *       - There's a space between each value.
 */

Task 3

Create a 2D array with 100 rows and 10 columns. Then, call print2DArray.

Task 4

Using a nested loop, populate the array with random numbers before calling: print2DArray.

Good Luck!
