Ever since Java 8 introduced default in addition to static methods inwards JDK 8, it's boot the bucket possible to define non-abstract methods inwards interfaces. Since in Java, ane flat tin implement multiple interfaces in addition to because at that spot tin live on concrete methods inwards interfaces, the diamond work has surfaced again. What volition come about if 2 interface has methods o the same refer in addition to a Java flat inherit from it? Many Java programmer too asks me the enquiry that, is Java eight is too supporting multiple inheritances of classes? Well, it's non but the incertitude is genuine because interface alongside methods is similar to abstract flat or inwards that whatsoever Class inwards Java.
In theory, it does await similar that but inwards detail, yous volition uncovering that Java designers convey made certain that the diamond work should non occur because of default methods on the interface from Java eight onwards.
If yous await closely, yous volition uncovering that multiple inheritances of classes are not supported inwards Java 8, instead, the compiler volition exercise additional checks to avoid ambiguity inwards calling default methods in addition to Diamond problem, which could come upwards if a flat implements 2 interface which contains the default methods alongside the same name.
We'll explore this concept alongside a proper code instance inwards the coming department but allow me order yous that this characteristic is hence underrated notwithstanding it has made the biggest affect inwards damage of evolving JDK API.
Without default in addition to static methods on an interface, it wasn't possible to add together novel methods on an interface in addition to seat the years of learning Java designer has later publishing JDK API.
Now, nosotros convey methods similar putIfAbsent() on Map interface in addition to comparing() on Comparator flat which makes twenty-four hr menses to twenty-four hr menses coding inwards Java to a greater extent than effective. All this is possible because of default methods in addition to static methods on the interface.
Btw, Java eight is non merely most default methods, it's amount of useful features similar lambda expressions, Stream API, novel Date Time API in addition to many tiddler API changes like join() method on String. If yous are interested to larn those gems, I propose yous join courses)5 Books to Learn Java eight from Scratch (books) How to bring together String inwards Java eight (example) How to utilisation filter() method inwards Java eight (tutorial) How to format/parse the engagement alongside LocalDateTime inwards Java 8? (tutorial) How to utilisation Stream flat inwards Java eight (tutorial) How to convert List to Map inwards Java eight (solution) 20 Examples of Date in addition to Time inwards Java eight (tutorial) How to utilisation peek() method inwards Java eight (example) How to variety the map yesteryear keys inwards Java 8? (example) How to variety the may yesteryear values inwards Java 8? (example) 10 examples of Optional in Java 8? (example) Difference betwixt abstract flat in addition to interface inwards Java 8?

P.S.: If yous merely desire to larn to a greater extent than most novel features inwards Java eight in addition to hence delight come across the course What's New inwards Java 8. It explains all the of import features of Java eight e.g. lambda expressions, streams, functional interfaces, Optional, novel Date Time API in addition to other miscellaneous changes.
