Before we jump into the technicalities, it would be best we understand what Java JDK is. Java Development Kit is, first and foremost, a Software Development Kit (SDK), which has been one of the most famous among the users. Now, Java JDK 12 and Java JDK 13 are the latest versions in the market. If we are to compare both the SDKs, there are some parameters that we will follow.
Of course, the first in that line would include the full specifications that each version is offering. Then there is the compatibility factor that also determines how much people use both the versions. So, in this article, we will be a little bit technical and figure out the fundamental differences between the two versions of JDK.

Fundamental Differences Between Them
It would be best if we understand the JDK 13 is primarily an upgrade of JDK 12. Therefore, more or less, every difference that we mention here is an upgraded feature. So, the features that we didn’t mention in JDK 13 are available in that version as well.
Here are some fundament differences between Java JDK 12 and Java JDK 13:
When it comes to the specs of JDK 12, it has tons of utility features like 684 new characters, 11 new blocks, and 7 new scripts. JDK 13, on the other hand, carry on all the specs the JDK 12 has.
Alongside that, the users will get 3 unique methods, which have been added to “java.nio.file.FileSystems.” That includes, “newFileSystem(Path)”, “newFileSystem(Path, Map<String, ?>)”, and “newFileSystem(Path, Map<String, ?>, ClassLoader)”.

The removal features of both versions have been fixed to a great extent. JDK 12 offers removal features like “com.sun.awt.SecurityWarning Class”, “finalize Methods from FileInputStream and FileOutputStream”, “finalize Method in java.util.ZipFile/Inflator/Deflator”, “GTE CyberTrust Global Root,” and “javac Support for 6/1.6 source, target, and release Values.”
JDK 13, along with all these removal features and options, also offer “awt.toolkit System Property”, “Runtime Trace Methods,” “VM option -XX+AggressiveOpts,” “T-Systems Deutsche Telekom Root CA 2 Certificate”, and many more.
Compatibility and Usability
There is no doubt that JDK 12 has more active users. It is due to the fact that JDK 12 released earlier than JDK 13. However, JDK 13, because of its significant upgraded features, has become a fan-favourite at a much less time. Both are compatible as Java always maintain a level of standards.
As we have mentioned before, JDK 13 is an upgrade to its predecessor – JDK 12. So, more or less, all the necessary features and functionalities are the same. However, JDK 13 is a massive upgrade.
Therefore, many functions, which were not possible before, the users can do that. After a few times, we will get the next version, where things would be better.
