Java is platforms independent, high level programming language. if you want to run java stuff, you need a extra Java run time environment(JRE) so this is add extra layer to your system and add extra possible security exploits but same time this gain platform independence feature. As long as you have JRE environment you can run your own program everywhere. Syntax is complicated I mean not easy as python programming language.

For example, for write something

Python
Print "Hello world"

Java
System.out.print("Hello world");

So if you are new and want to learn fast fundamentals programming, you must start with python.

Can someone tell me why is this programming language not open-source?

reply

At least as of 2018, Java is truly open-source.

"OpenJDK is licensed under the GNU GPL. As of Java SE 7, OpenJDK is the official Java reference implementation."
-- https://en.wikipedia.org/wiki/Java_ (programming_language)

Much like RedHat "sells" Linux, but Linux is entirely open source, Oracle also "sells" Java, but Java is entirely open source. Oracle does provide some non-free tools and non-free builds of OpenJDK, and they offer paid support for Java. But, you can always download Java for free (no adware, no licensing fees) from https://openjdk.java.net/ (e.g. https://jdk.java.net/11/ ).

A very big problem with Java is, that installing a new update in most cases didn’t uninstall the older version.
This meant that, despite installing the “latest and greatest” version, the security exposures still remained.

My last hope is, that the german instruction to uninstall Java in case of a DLL-errormessage can help:

  • Search all folders (Index Your Files: Size "0 kb to 0 kb" finds folders) with "Java" in the folder-name
  • Delete all folders with "Java" on C:\ but not folders with "Java" stored from other apps (e.g. from Gladinet C.D.)
  • Delete all registry-entries with "Java" but not in connection with folders with "Java" stored from other apps
