Practice 1: Two-Dimensional Array with Initializer List

• Trace the provide code segment and predict the output.
• Verify your prediction is correct by running the code in the Java Playground.
• Add output statements to print the value in the upper left corner and lower right corner of the 2D array. Use the length constant to compute the lower right corner.
• Run the code to verify your statements are correct.

Practice 2: Jagged Two-Dimensional Array

• Trace the provide code segment and predict the output.
• Verify your prediction is correct by running the code in the Java Playground.

Practice 3: Initial Values

• Trace the provide code segment and predict the output.
• Verify your prediction is correct by running the code in the Java Playground.
• Modify the code to make the 2D array be of type double. Predict the output and run the code to check.
