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

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

    This chapter is from the bespeak 

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

    The key points of this chapter are:

  • The main intuition for using a lambda expression is to suspend the execution of the code until an preempt time.
  • When a lambda expression is executed, Make sure 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 recrudesce an instance of a functional interface.
  • When you drudgery with transformations, esteem how you can compose them.
  • To compose transformations lazily, you requisite to maintain a list of bar not anyone pending transformations and apply them in the end.
  • If you requisite to apply a lambda many times, you often acquire a random to split up the drudgery into subtasks that execute concurrently.
  • Think what should betide when you drudgery with a lambda expression that throws an exception.
  • When working with generic functional interfaces, use ? super wildcards for controversy types, ? extends wildcards for recrudesce types.
  • When working with generic types that can exist transformed by functions, esteem supplying map and flatMap.
  • The point of bar not anyone lambdas is deferred execution. After all, if you wanted to execute some code perquisite now, you’d execute 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 perquisite 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 capable view to believe through what you want to achieve when you set out programming with lambdas.

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

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

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

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

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

    Now they requisite to write a manner that

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

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

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