Gets the computer to repeat some statements over and over again (for instance, a certain number of times). With the release of Java 9, the language has ten new words, called restricted keywords. A restricted keyword has a specific meaning in the language, but only if you use that word in a specific way. For example, if you writeOkay, jokes aside. If you expect a profound explanation in a serious tone of voice, try this one. This book introduces you to the core terms of Java and guides you from the basic understanding of data types, classes, and objects to more complex concepts like lambda expressions and functional interfaces. This book also has a self-test section at the end of each chapter. You may have noticed that not all top professionals can be also top teachers. Sometimes too experienced specialists can't explain any concept they know to a complete beginner… only because they can’t keep it simple. W3Schools is optimized for learning and training. Examples might be simplified to improve reading and learning. You can reuse any of these names for any purpose in your code. But if you do, you might have trouble using a name with its normal meaning from the Java API.
