Now, Java programmers can specify the same immutable rules for their own objects by calling them “ Records.” This simplifies multi-threaded safety, caching, and synchronization.

The C programming language is the polar opposite to Java in these two respects. First, C code is compiled to native machine code and doesn’t require the use of a virtual machine for interpretation.

"Java is much more programmer-friendly than C or C++, or was for a few years there until they made just as complicated. It's become arguably even harder to learn than C++," Andreessen said.

Amazon Web Services has long offered an SDK to make it easier to access its web services from Java. Now it has another lure for Java programmers: James Gosling, the father of Java.
