What functions does Java cost?

Recently, Oracle announced that "after January 2019", if it does not obtain a commercial license from Oracle, Java SE 8 will no longer receive public updates and will not be used for "commercial or production use”. Java, which has been used for 23 years, will no longer be free. What’s going on?

Java, which is now the leading language in the programming language world, is not only equipped with a rocket-like update speed, but now it also intends to allow users to pay for tickets. As early as April 2018, Oracle announced that starting from January 2019, Java SE 8 public updates will not be provided for business, commercial or production use without a commercial license. That is to say, if developers still want to use JDK 8 in the future, Oracle will not provide free technical support and will need to charge additional fees.

If you still want to continue using Java 8 for free, you can only make the following two choices:

1. No more updates and continue to use Oracle JDK indefinitely 8;

2. Use free Java SE 8 / OpenJDK 8 binary distributions from other service providers.

Faced with the fact that JDK 8 is about to stop free update support and JDK 11 is not commercially available, many developers may be curious as to why Java, which has been used for 23 years, is no longer free?

On the one hand:

Oracle JDK 8 version was released in March 2014 and officially entered the "End of Public Updates" in January 2019. This version Oracle supports After nearly 5 years, one version of the software cannot be supported indefinitely, because the maintenance cost will be too high.

On the other hand:

It may be that not many people buy Oracle's Java SE Advanced, Java SE Advanced Desktop or Java SE Suite. The name is very long and a bit confusing. To put it simply, this is a paid service. It is an advanced tool and function provided by Oracle for enterprise-level users. It can monitor, deploy, and manage enterprise-level Java programs. In other words, if you purchase this service, you don't have to worry about JDK Update charges. But the problem is that not many people will buy this service, which leads Oracle to make this move.
