Many organizations that rely on Java are switching from the Oracle JDK to OpenJDK and taking advantage of significant cost savings in the process.

When I retired from the classroom in 2021, I had no intention of sitting on a rocking chair on my front porch.

I also wanted to write a book. I approached a number of publishers with my idea for a beginner’s book. I even wrote a sample chapter and publsihed it on my blog, https://www.omnijava.com/2021/10/20/java-for-beginners-my-unsuccessful-book-proposal/ .
