- Summary
After we got a few new String methods in Java 11 and the Files.readString() and writeString() methods, the JDK developers extended both classes again for Java 12.
For some requirements, you may want to terminate a Stream with two collectors instead of one and combine the result of both collectors. In the following example source code, we want to determine the difference from largest to smallest number from a stream of random numbers (we use Optional.orElseThrow() introduced in Java 10to avoid a "code smell" ...
Using the static method NumberFormat.getCompactNumberInstance(), we can create a formatter for the so-called "compact number formatting". This is a form that is easy for humans to read, such as "2M" or "3 billion". The following example shows how some numbers are displayed – once in the short and once in the long compact form: The program will prin...
The following improvements ensure that our Java applications start faster, have lower garbage collector latencies, and a better memory footprint.
This section lists experimental features and previews, i.e., functionality that are still in the development stage and may be modified based on feedback from the Java community until the final release. Instead of going into detail about these features, I will refer to the Java version where the respective features are released as "production-ready"...
In this section, I list changes that will not affect the daily work of most Java developers. However, it is certainly not wrong to have skimmed over the changes once.
The changes in Java 12 are pretty manageable. We got a few new String and Filesmethods and the Teeing Collector, which allows us to terminate a Stream over two collectors and combine their results. Class data sharing is now enabled by default, thanks to the classes.jsashared archive file provided on 64-bit systems. The G1 Garbage Collector can abor...
