What is the most effective way for float and double comparison?
...e spent a long time tracing a bugs in a system that presumed a==b if |a-b|<epsilon. The underlying problems were:
The implicit presumption in an algorithm that if a==b and b==c then a==c.
Using the same epsilon for lines measured in inches and lines measured in mils (.001 inch). That is a==b b...
Java Equivalent of C# async/await?
...
@rozar: No, not really. There are already multiple options for asynchrony - but RxJava doesn't change the language in the way that C# did. I have nothing against Rx, but it's not the same thing as async in C# 5.

List<T>
Collections.emptyList() was added in Java 1.5 and it is probably always preferable. This way, you don't need to unnecessarily cast around within your code.
Collections.emptyList() intrinsically does the cast for y...

Note that you cannot read the response stream so you have to add a filter to the Output stream and capture a copy.

Hidden Features of C#? [closed]

lambdas and type inference are underrated. Lambdas can have multiple statements and they double as a compatible delegate object automatically (just make sure the signature match) as in:
Console.CancelKeyPress +=
(sender, e) => {
Console.WriteLine("CTRL+C detected!\n");
