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

    This chapter shows how to create your own Java libraries that accomplish utilize 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 utilize of them. In this chapter, you will learn how to create your own libraries that accomplish utilize of lambda expressions and functional interfaces.

    The key points of this chapter are:

  • The main intuition for using a lambda expression is to defer the execution of the code until an commandeer time.
  • When a lambda expression is executed, accomplish certain 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 labor with transformations, reckon how you can compose them.
  • To compose transformations lazily, you need to retain a list of totality pending transformations and apply them in the end.
  • If you need to apply a lambda many times, you often absorb a random to split up the labor into subtasks that execute concurrently.
  • Think what should happen when you labor with a lambda expression that throws an exception.
  • When working with generic functional interfaces, utilize ? super wildcards for argument types, ? extends wildcards for recur types.
  • When working with generic types that can subsist transformed by functions, reckon supplying map and flatMap.
  • The point of totality lambdas is deferred execution. After all, if you wanted to execute some code privilege 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 divide 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 first-rate project to speculate through what you want to achieve when you set out programming with lambdas.

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

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

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

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

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

    Now they need to write a course that

  • Accepts the lambda
  • Checks whether it should subsist called
  • Calls it when necessary
  • To accept the lambda, they need 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 first-rate choice is a Supplier<String>. The following course provides indolent logging:

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

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