ArrayList Tutorial

Practice 1: Managing a Guest List

• Trace the provide code segment and predict the output.
• Verify your prediction is correct by running the code in the Java Playground.
• Add the following guests to the list: "Heather", "Chad", and "Ana" and print the ArrayList.
• Predict the output of your code segment and then run it in the Java Playground to test your prediction.

Practice 2: Animal List

• Trace the provide code segment and predict the output.
• Verify your prediction is correct by running the code in the Java Playground.
• Remove "cat" from the list and add "horse" to the beginning of the list.
• Predict the output and verify your prediction by running the code in the Java Playground.

Practice 3: Add Numbers

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

Practice 4: Changing Numbers

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

Practice 5: Remove Numbers

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