Java 1 8 features

All the knowledge and tools before they can understand complex concepts like multi-threading and concurrency.It covers all essential Java 8 features described above in bootcamp style with a lot of focus on hands-on work.If you can afford it, then this is the best course to learn Java online. To be honest, it's dirt cheap, even one day Java class cost around $100 in developing countries, forget about developing country. You can't get a comprehensive Java course less expensive than this.I personally recommend Head First Java 3rd Edition to all beginners when it comes to books, as I have learned a lot from it myself. It's a great book to start if you don't know anything about Java, but unfortunately, it's not up-to-date.Once you have gone through this book, you can pick any good Java books to learn key Java 8 features like lambda expression, method reference, Stream API, new Date, and Time API, default methods, etc.The content is still valid, and Java Fundamentals have not changed, but I strongly suggest every programmer start with the latest Java version. Java 8 or Java 9 and on that parameter Modern Java in Action is currently the best book to learn Java.This book covers each topic in good depth. I even encourage you to read all three books by this author on Java 8 to learn Java 8 in depth.You can also take a look at the official Java tutorials offered by Oracle. These tutorials are both comprehensive, up-to-date, and covered almost all crucial details of the Java programming language. Further, you can use Google along with your learning.If you need to understand a particular concept, term, or any issue with Java, Google can point you to a specific resource. There are lots of blogs, tutorial sites, and free video tutorials on the internet to learn Java programming.I have also created The Complete Java Developer RoadMap to take you from beginner to professional Java developer. That roadmap includes everything a Java programmer needs to learn like topics, tools, technologies, and libraries.Few More Java Resources you may likeThe Complete Java Masterclass on UdemyJava Fundamentals Part 1 and Part 210 Things Java Programmer should learn in 2025Official JDK 10 Documentation5 Books to Learn Java 8 and Functional ProgrammingTop 10 Courses to learn Java in 20255 Free Java Online Courses for Beginner5 Essential Frameworks Java Developer Should Learn 5 Books to Learn Core Java from Scratch10 Frameworks Java Programmer should learn My favorite Courses to learn Spring Boot10 Free Courses to Learn Spring Framework10 Tools Every Java Programmer Should KnowObject-Oriented Java Programming: Data Structures and BeyondThanks for reading this article so far.

Could write their Android apps using Java 7 features and libraries.2. Android versions 7.0 to 8.1 (Nougat, Oreo, and Oreo MR1): – With the release of these Android versions, the platform provided support for Java 8 features as well. Developers could now use features like lambda expressions, functional interfaces, and the stream API while targeting these versions.3. Android versions 9.0 to 10.0 (Pie, Android 10): – Starting from Android Pie, the platform introduced limited support for selected Java 8 language APIs, such as some new language features, but there were still missing APIs.4. Android versions 11.0 and later: – Android 11 and subsequent versions offer enhanced support for Java 8 language APIs, including a majority of the Java 8 language and library APIs.In summary, the version of Java available for Android depends on the Android version being used. Older versions primarily support Java 7, while newer versions, starting from Android 7.0, gradually introduced support for Java 8 language features and libraries. It’s important for developers to consider the target Android version and its corresponding Java compatibility when working on Android app projects.

The "unsupported major.minor version 55.0" error started to come after Java SE 11 release and the root cause of this error is trying to run a Java application compiled with JDK 11 into a JRE lower than Java SE 11 like JRE 9 or JRE 8. This is very common because a developer has updated their compiler or IDE to Java SE 11 but many times their runtime is not upgraded to Java 11. If you remember, in Java you can run a class file compiled with a lower version say Java 8 to a higher version say JRE 11 because Java is backward compatible but vice-versa is not allowed. I mean, you cannot run a JAR file or class file created by Java 11 version into Java 8 or Java 9 version. Similarly, you cannot run a Java SE 17 compiled class file in Java SE 11 or Java SE 13 runtime environment.This makes sense because every Java version has unique features. For example, Java SE 8 has features like lambda expressions, method reference, functional interface, and new Date and Time API, which lower version JRE has no information. Depending upon where you getting this error like Eclipse, NetBeans, IntelliJ IDEA, or Android Studio, the solution could be different. All these IDEs have different settings for JRE but the bottom line is the same, you need to configure these IDE to use JRE 8 to run the Java program compiled using Java 8.The root causes of any java.lang.UnsupportedClassVersionError is
