The service locator itself might be asingleton. There usually is no need to have two instances of a service locator. Lazy initializationof services might be considered. In the example above, the constructor creates new instances for all possible services; initialization might be deferred until some...
You can userelational patternsto test how a value compares to constants. For example, the following code returns the state of water based on the temperature in Fahrenheit: C# stringWaterState(inttempInFahrenheit)=> tempInFahrenheitswitch{ <32=>"solid",32=>"solid/liquid transition", (>32)and...
Example 4.12.4-1. Final Variables Declaring a variable final can serve as useful documentation that its value will not change and can help avoid programming errors. In this program: class Point { int x, y; int useCount; Point(int x, int y) { this.x = x; this.y = y; } static ...

I’ll explain the need for @unchecked in a moment. Finally, we can use pattern bindings with a regular expression to decompose a string. Here’s an example for parsing (simple!) SQL strings: // src/script/scala/progscala3/patternmatching/AssignmentsRegex.scala scala> val c = """\*|[...

Non default clauses have an implicit null check (**). In the example before the very last case clause is valid because it matches only when the argument is notnull. (**) The very last case clause shows another feature added to C# 7 called “discard” pattern. The name_is special and...
