Achieve Syntax Brevity with Anonymous Classes and Instance Initializers

Why Trust Us

The first listing here, which may look more familiar, is considerably longer than the second listing, even though they’re essentially equivalent. 

Listing 1.List friends = new ArrayList();friends.add("Ben");friends.add("Kiran");friends.add("....");

You can replace all the code in Listing 1 with an anonymous class that uses an instance initializer as shown in Listing 2.

Listing 2.new ArrayList(){{add("Ben");add("Kiran");add("....");}};
