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.

Practice 1: Update Inventory

  • Analyze the provided code segment and predict the output.
  • Try the code in the Java Playground to verify your prediction.
  • The store wants to increase all of the prices. Write program code to increase all the prices by 0.25.
  • Analyze the code segments and predict the output. Verify your prediction by running it in the Java Playground.
  • The cost of apples was entered incorrectly. Change the price of the apples to 2.75.
  • Analyze the code segments and predict the output. Verify your prediction by running it in the Java Playground.
