...ntBag<int> monitorOut = new ConcurrentBag<int>();
var arrayStrings = new string[1000];
Parallel.ForEach<string>(arrayStrings, someString =>
{
monitor.Add(monitor.Count);
monitor.TryTake(out int result);
monitorOut.Add(result);
});

Java: Class.this

How to Generate unique file names in C#
...
If readability doesn't matter, use GUIDs.
E.g.:
var myUniqueFileName = string.Format(@"{0}.txt", Guid.NewGuid());
or shorter:
var myUniqueFileName = $@"{Guid.NewGuid()}.txt";
In my programs, I sometimes try e.g. 10 times to generate a readable name ("Image1.png"…"Image10.png") and if that...
Why is Java's Iterator not an Iterable?
...o.
For example, I can usually write:
public void iterateOver(Iterable<String> strings)
{
for (String x : strings)
{
System.out.println(x);
}
for (String x : strings)
{
System.out.println(x);
}
}
That should print the collection twice - but with you...
Cleaner way to update nested structures
...nt = 3, superMode: Boolean = false)
scala> @zip case class Game(state: String = "pause", pacman: Pacman = Pacman())
scala> val g = Game()
g: Game = Game("pause",Pacman(3,false))
// Changing the game state to "run" is simple using the copy method:
scala> val g1 = g.copy(state = "run")

Default constructor vs. inline field initialization
...and more straight :
public class Foo {
private int x = 5;
private String[] y = new String[10];
}
than the constructor way :
public class Foo{
private int x;
private String[] y;
public Foo(){
x = 5;
y = new String[10];
}
}
In real classes with so real sp...
What is the purpose of Rank2Types?
...y only use it as monomorphic. In the example map uses id as if it had type String -> String. And of course you can also pass a simple monomorphic function of the given type instead of id. Without rank2types there is no way for a function to require that its argument must be a polymorphic function...
How to implement a tree data-structure in Java? [closed]
...t; children;
}
}
That is a basic tree structure that can be used for String or any other object. It is fairly easy to implement simple trees to do what you need.
All you need to add are methods for add to, removing from, traversing, and constructors. The Node is the basic building block of ...
