We can annotate disabled methods which throw `UnsupportedOperationException` (i.e mutation methods on `Collection`) in order to provide an extra clue for static analyzers and IDEs about them.
I think we should move some classes to `cactoos-matchers` instead of keep them in `cactoos`. My list: - `BehavesAsCollection` - `BehavesAsList` - `EmptyClosableReader` - `FakeHandler` - `FakeLogger` - `BehavesAsMap` -...
Now, we've a class `Abbreviated` which does something like: `It's a very long phrase so it should be abbrevia...". But we can want abbreviate for left, like: `Reading file .../abc/cdef/fgh/File.docx`....
The javadoc states that `collection.NoNulls` is `A decorator of {@link Collection} that tolerates no NULLs.` Does this mean it tolerates no `null`s in the underlying collection or just as arguments...
[`ListOf`](https://github.com/yegor256/cactoos/blob/master/src/main/java/org/cactoos/list/ListOf.java), [`MapOf`](https://github.com/yegor256/cactoos/blob/master/src/main/java/org/cactoos/map/MapOf.java), and [`SetOf`](https://github.com/yegor256/cactoos/blob/master/src/main/java/org/cactoos/set/SetOf.java) all contain some variation of a loop that assigns the values of the `src` argument to the wrapped `Collection` in their constructors. As I understand it,...
I see a lot of this (bellow) code repeat over and over: ``` @Override public boolean equals(final Object other) { return new Unchecked( new Or( () -> other == this,...
Let's remove private `copy()` and `copyPartial()` from `TailOf` an put `TeenInput` instead. If it's no applicable, let's create a `Copy` and maybe `PartialCopy` classes.
Is it possible to have a smart class for Text which realizes concept of printer? https://www.yegor256.com/2016/04/05/printers-instead-of-getters.html ```java final class Print implements Text { private final Text text; public Print(final Text...
[Here](https://github.com/yegor256/cactoos/blob/master/src/main/java/org/cactoos/func/Async.java#L75) in `Async` it creates a new `ExecutorService` and [here](https://github.com/yegor256/cactoos/blob/master/src/main/java/org/cactoos/func/Async.java#L90) it submit the `Func` to `Executor` but it doesn't shutdown the `ExecutorService`. So I think it should call `this.executor.shutdown()` after...
Current TextOf has the following public constructor: ``` public TextOf(final Iterable iterable) { this( () -> new Joined( ", ", new Mapped( Object::toString, iterable ) ).asString() ); } ``` I...
