9.5 Programming Activity 1: Working with Two-Dimensional Arrays

In this activity, you will work with a 4-row, 20-column, two-dimensional array of integers. Specifically, you will write methods to perform the following operations:

  1. Fill the array with random numbers between 50 and 80.

  2. Print the array.

  3. Set every array element of a given row to a specified value. The value is a parameter of a method.

  4. Find the minimum value in a given column of the array. The column is a parameter of a method.

  5. Count the number of elements of the array having a specified value. The value is a parameter of a method.

The framework for this Programming Activity will animate your algorithm so that you can check the accuracy of your code. For example, Figure 9.13
