Write Code Segments that Require ArrayList Objects

Your Turn

• Write program code to complete the provided tasks.
• While these problems can be solved using other loop types, use a for loop to solve them.
• 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.
