Write Code Segments that Require Two-Dimensional Arrays

Your Turn

• Write program code to complete the provided tasks.
• Run the code in the Java Playground to see if your code generates the desired result.
• Make necessary changes until you have satisfied the tasks.

Introduction to Two-Dimensional Array Tutorial

Practice 1: Temperatures Array

• Write a code segment that initializes a 7x24 double array for storing hourly temperatures over a week and sets all values to 0.0 as a default.
• Try the code in the Java Playground to verify your prediction.

Practice 2: Alternating True and False

• Create a boolean[][] board that is a 5x5 two-dimensional array. The values should alternate between true and false. Even rows will start with true and odd rows will start with false.
• Try the code in the Java Playground to verify your prediction.
