Microsoft was not directly involved in developing Java, but they did have some projects and offerings related to Java development. Here are a few key points regarding Microsoft and Java:

1. Azure SDK for Java: Microsoft provides an Azure SDK for Java, which is a set of libraries and tools that developers can use to build Java applications that interact with Microsoft Azure cloud services.

2. Visual Studio Code: Microsoft’s popular code editor, Visual Studio Code (VS Code), has extensive support for Java through various extensions. These extensions enable Java developers to work with Java projects and code effectively.

3. OpenJDK and AdoptOpenJDK: Microsoft, along with other companies, supports the AdoptOpenJDK initiative, which aims to provide freely available prebuilt OpenJDK binaries.

4. Minecraft: Microsoft acquired the popular game Minecraft, which was developed in Java. After the acquisition, there have been some developments to support Minecraft’s Java Edition, but the core development of the game itself remains largely unchanged.

5. Microsoft JVM (Java Virtual Machine): In the past, Microsoft had its own JVM implementation, known as Microsoft JVM. However, it was discontinued, and Microsoft now recommends using Oracle’s or OpenJDK’s JVMs for Java development.
