Chapter 7 – Arrays and ArrayLists

• InitArray.java uses keyword new to create an array of 10 int elements, which are initially zero
• InitArray.java creates an array and initialize its elements with an array initializer – a comma-separated list of expressions (called an initializer list) enclosed in braces
• InitArray.java creates a 10-element array and assigns to each element one of the even integers from 2 to 20 (2, 4, 6, ..., 20)
• SumArray.java two variations on for loop
• StudentPoll.java illustrates ArrayIndexOutOfBoundsException, see also version 2 which uses the alternative for loop.
• ArrayListCollection.java demonstrates the use of ArrayList

Other

• BarChart.java using bar charts to display array data graphically
• RollDie.java use counter variables to summarize data
