The Oracle® Java Micro Edition (Java ME) Software Development Kit (SDK) is a natural starting point for learning and using Java ME technology. The focus of the SDK is to provide emulation and deployment assistance during the development process. This chapter introduces the SDK and provides a quick introduction to using the SDK.Using this simple yet powerful tool you can create, edit, compile, package, and sign an application. After testing your application in the Oracle Java ME SDK emulation environment, you can move to deploying and debugging on an external device.This chapter provides information you need to ensure that your Microsoft Windows XP (32-bit) or Windows 7 (32-bit or 64-bit) platform is correctly set up for working with Oracle Java ME SDK. Both Windows XP and Windows 7 must include the most recent Microsoft service packs.1.1 Installing the Java SE PlatformTo properly run the Oracle Java ME SDK software and its associated Tools, you must have Java Platform, Standard Edition (Java SE), Version 7, Update 11 (or later) installed on your computer.This guide assumes you have already installed the Java SE platform. If you have not installed Java SE, you can download it from the following location: Java SE platform must also be in your PATH.1.1.1 Setting and Verifying Your Java SE PATHTo verify if Java SE platform is set in your PATH:In the Windows command line, type:C:\>echo %PATH%If Java SE is properly installed, you see a path to the default installation directory:C:\>Program Files\Java\jdk1.7.0_xIf not, you need to add Java

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
