    Java SE 8 for the Really Impatient: Programming with Lambdas | killexams.com true questions and Pass4sure dumps

    This chapter shows how to create your own Java libraries that outcome consume of lambda expressions and functional interfaces.

    This chapter is from the book 

    In the first two chapters, you saw the basic syntax and semantics of lambda expressions as well as the stream API that makes extensive consume of them. In this chapter, you will learn how to create your own libraries that outcome consume of lambda expressions and functional interfaces.

    The key points of this chapter are:

  • The main understanding for using a lambda expression is to shelve the execution of the code until an arrogate time.
  • When a lambda expression is executed, outcome confident to provide any required data as inputs.
  • Choose one of the existing functional interfaces if you can.
  • It is often useful to write methods that recur an instance of a functional interface.
  • When you toil with transformations, reckon how you can compose them.
  • To compose transformations lazily, you necessity to maintain a list of everybitof pending transformations and apply them in the end.
  • If you necessity to apply a lambda many times, you often maintain a casual to split up the toil into subtasks that execute concurrently.
  • Think what should happen when you toil with a lambda expression that throws an exception.
  • When working with generic functional interfaces, consume ? super wildcards for dispute types, ? extends wildcards for recur types.
  • When working with generic types that can exist transformed by functions, reckon supplying map and flatMap.
  • The point of everybitof lambdas is deferred execution. After all, if you wanted to execute some code privilege now, you’d conclude that, without wrapping it inside a lambda. There are many reasons for executing code later, such as

  • Running the code in a sever thread
  • Running the code multiple times
  • Running the code at the privilege point in an algorithm (for example, the comparison operation in sorting)
  • Running the code when something happens (a button was clicked, data has arrived, and so on)
  • Running the code only when necessary
  • It is a superb design to reflect through what you want to achieve when you set out programming with lambdas.

    Let us inspect at a simple example. Suppose you log an event:

    logger.info("x: " + x + ", y: " + y);

    What happens if the log smooth is set to stifle INFO messages? The message string is computed and passed to the info method, which then decides to throw it away. Wouldn’t it exist nicer if the string concatenation only happened when necessary?

    Running code only when necessary is a consume case for lambdas. The measure idiom is to wrap the code in a no-arg lambda:

    () -> "x: " + x + ", y: " + y

    Now they necessity to write a system that

  • Accepts the lambda
  • Checks whether it should exist called
  • Calls it when necessary
  • To accept the lambda, they necessity to pick (or, in rare cases, provide) a functional interface. They argue the process of choosing an interface in more detail in Section 3.3, “Choosing a Functional Interface,” on page 50. Here, a superb option is a Supplier<String>. The following system provides sluggish logging:

    public static void info(Logger logger, Supplier<String> message) { if (logger.isLoggable(Level.INFO)) logger.info(message.get()); }

    We consume the isLoggable system of the Logger class to determine whether INFO messages should exist logged. If so, they invoke the lambda by calling its abstract method, which happens to exist called get.
