[lambda-expression]

The new and significant lambda expression feature of Java was added in Java SE 8. It offers a simple and direct approach to using an expression to represent one method interface. In a library's collection, it is quite helpful. It is advantageous to filter, iterate, and extract data from a collection.

Consistency and Reducibility: Which is the theorem and which is the lemma?

Here's an example from programming language theory which I think is an interesting case study about how "stories" work in mathematics. Even if a given theorem is unambiguously defined and certainly true, the ways people contextualize it can still differ.

To set the scene, there is an idea that typed programming languages correspond to logics, so that a proof of an implication A→B corresponds to a function of type A→B. For example, the typing rules for simply-typed lambda calculus are exactly the same as the proof rules for minimal propositional logic, adding an empty type Void makes it intuitionistic propositional logic, by adding "dependent" types you get a kind of predicate logic, and really a lot of different programming language features also make sense as logic rules. The question is: if we propose a new programming language feature, what theorem should we prove in order to show that it also makes sense logically?

The story I first heard goes like this. In order to prove that a type system is a good logic we should prove that it is consistent, i.e. that not every type is inhabited, or equivalently that there is no program of type Void. (This approach is classical in both senses of the word: it goes back to Hilbert's program, and it is justified by Gödel's completeness theorem/model existence theorem, which basically says that every consistent theory describes something.)

Usually it is obvious that no values can be given type Void, the only issue is with non-value expressions. So it suffices to prove that the language is normalizing, that is to say every program eventually computes to a value, as opposed to going into an infinite loop. So we want to prove:

If e is an expression with some type A, then e evaluates to some value v.

Naively, you may try to prove this by structural induction on e. (That is, you assume as an induction hypothesis that all subexpressions of e normalize, and prove that e does.) However, this proof attempt gets stuck in the case of a function call like (λx.e₁) e₂. Here we have some function (λx.e₁) : A→B and a function argument e₂ : A. The induction hypothesis just says that (λx.e₁) normalizes, which is trivially true since it's already a value, but what we actually need is an induction hypothesis that says what will happen when we call the function.

In 1967 William Tait had a good idea. We should instead prove:

If e is an expression with some type A, then e is reducible at type A.

"Reducible at type A" is a predicate defined on the structure of A. For base types, it just means normalizable, while for function types we define

e is reducable at type A→B ⇔ for all expressions e₁, if e₁ is reducible at A then (e e₁) is reducible at B.

For example, an function is reducible at type Bool→Bool→Bool if whenever you call it with two normalizing boolean arguments, it returns a boolean value (rather than looping forever).

This really is a very good idea, and it can be generalized to prove lots of useful theorems about programming languages beyond just termination. But the way I (and I think most other people, e.g. Benjamin Pierce in Types and Programming Languages) have told the story, it is strictly a technical device: we prove consistency via normalization via reducibility.

❧

The story works less well when you consider programs that aren't normalizing, which is certainly not an uncommon situation: nothing in Java or Haskell forbids you from writing infinite loops. So there has been some interest in how dependent types work if you make termination-checking optional, with some famous projects along these lines being Idris and Dependent Haskell. The idea here is that if you write a program that does terminate it should be possible to interpret it as a proof, but even if a program is not obviously terminating you can still run it.

At this point, with the "consistency through normalization" story in mind, you may have a bad idea: "we can just let the typechecker try to evaluate a given expression at typechecking-time, and if it computes a value, then we can use it as as a proof!" Indeed, if you do so then the typechecker will reject all attempts to "prove" Void, so you actually create a consistent logic.

If you think about it a little longer, you notice that it's a useless logic. For example, an implication like ∀n.(n² = 3) is provable, it's inhabited by the value (λn. infinite_loop()). That function is a perfectly fine value, even though it will diverge as soon as you call it. In fact, all ∀-statements and implications are inhabited by function values, and proving universally quantified statements is the entire point of using logical proof at all.

❧

So what theorem should you prove, to ensure that the logic makes sense? You want to say both that Void is unprovable, and also that if a type A→B is inhabited, then A really implies B, and so on recursively for any arrow types inside A or B. If you think a bit about this, you want to prove that if e:A, then e is reducible at type A... And in fact, Kleene had already proposed basically this (under the name realizability) as a semantics for Intuitionistic Logic, back in the 1940s.

So in the end, you end up proving the same thing anyway—and none of this discussion really becomes visible in the formal sequence of theorems and lemmas. The false starts need to passed along in the asides in the text, or in tumblr posts.

[codeline24]

Two paradigms rule programming: imperative and declarative.

Declarative emerged to address imperative's drawbacks. The imperative paradigm, also known as the procedural, is the oldest and most widely used approach to programming. It's like giving step-by-step instructions to a computer, telling it what to do and how to do it, one command at a time. It's called "imperative" because as programmers we dictate exactly what the computer has to do, in a very specific way. Declarative programming is the direct opposite of imperative programming in the sense that the programmer doesn't give instructions about how the computer should execute the task, but rather on what result is needed. Two main subcategories are functional and reactive programming. Functional programming is all about functions (procedures with a specific set of functionalities) and they can be assigned to variables, passed as arguments, and returned from other functions. Java offers libraries and frameworks that introduce functional programming concepts like lambda expressions and streams. Reactive programming is a programming paradigm where the focus is on developing asynchronous and non-blocking components. Back in the year 2013, a team of developers, lead by Jonas Boner, came together to define a set of core principles in a document known as the Reactive Manifesto. With reactive streams initiatives that are incorporated in Java specifications there are frameworks (RxJava, Akka Streams, Spring WebFlux..) that provide reactive paradigm implementation to Java.

Exploring Java Streams and Lambda Expressions

If you're looking to build a strong foundation in modern Java development, enrolling in the Best Java training institute in Hyderabad is a wise step forward. Java has evolved significantly over the years, and one of the most powerful features introduced in Java 8 is the combination of Streams and Lambda Expressions. These features allow developers to write cleaner, more efficient, and more readable code.

Understanding Java Streams

The Java Streams API provides a modern abstraction for handling collections and sequences of data.Instead of relying on traditional for-loops and if-statements, Streams offer a declarative approach to data processing.A developer can perform complex operations in a fluent and chainable manner by utilizing methods like filter(), map(), and reduce(). This results in less boilerplate code and more focus on the logic of what needs to be done.

Power of Lambda Expressions

With Lambda Expressions, Java became more expressive by introducing a new way to write anonymous methods. They are especially useful when working with functional interfaces and can significantly simplify event handling and collection manipulation. By allowing you to pass behavior as parameters, Lambdas make your code more compact and readable.

Combining Streams and Lambdas

The real power of Java 8 is realized when Streams and Lambdas are used together. This combination enables you to write powerful data processing pipelines in just a few lines of code. Whether you're filtering data from a list or transforming elements of a collection, this duo offers a clean and elegant solution.
