Tuples group multiple values into a single compound value. The values within a tuple can be of any type and do not have to be of the same type as each other. Tuples are created by grouping any amount of values: let tuple = ("one", 2, "three") // Values are read using index n...

Functions can return tuples: func tupleReturner() -> (Int, String) { return (3, "Hello") } let myTuple = tupleReturner() print(myTuple.0) // 3 print(myTuple.1) // "Hello" If you assign parameter names, they can be used from the return value: func tupleReturner(...

Java SE 5 public enum Singleton { INSTANCE; public void execute (String arg) { // Perform operation here } } Enums have private constructors, are final and provide proper serialization machinery. They are also very concise and lazily initialized in a thread safe manne...

Preferences objects always represent a specific node in a whole Preferences tree, kind of like this: /userRoot ├── com │   └── mycompany │   └── myapp │   ├── darkApplicationMode=true │   ├── showExitConfirmation=false │   └── windowMaximized=true └── org └...

A value of a Preferences node can be of the type String, boolean, byte[], double, float, int or long. All invocations must provide a default value, in case the specified value is not present in the Preferences node. Preferences preferences = Preferences.userNodeForPackage(getClass()); String som...

To store a value into the Preferences node, one of the putXXX() methods is used. A value of a Preferences node can be of the type String, boolean, byte[], double, float, int or long. Preferences preferences = Preferences.userNodeForPackage(getClass()); preferences.put("someKey", "...

A very common guideline in object oriented design is "as little as possible but as much as necessary". This also applies to the strategy pattern: It is usually advisable to hide implementation details, for example which classes actually implement strategies. For simple strategies which do...

Method injection is a fine grained way of injecting dependencies into processing. Consider a method that does some processing based on the current date. The current date is hard to change from a test, so it is much easier to pass a date into the method that you want to test. public void ProcessRe...
