Motivation

JDK 8 added lambdas to alleviate the bulkiness of anonymous inner classes. We use lambdas heavily in 231.

Background

Lambda Expressions

Code To Investigate

async,finish

		launchApp(() -> {
			System.out.println("start");

			finish(() -> {
				async(() -> {
					sleepRandom(1_000);
					System.out.println("-apples");
				});
				async(() -> {
					sleepRandom(1_000);
					System.out.println("--oranges");
				});
				async(() -> {
					sleepRandom(1_000);
					System.out.println("---bananas");
				});
				async(() -> {
					sleepRandom(1_000);
					System.out.println("----mangoes");
				});
			});

			System.out.println("stop");
		});
