java17-features — Java 17 features with examples

Companion code for the ankurm.com article Java 17 Features with Examples: Records, Sealed Classes, Text Blocks, Switch Expressions. The explanation lives in the article; this folder holds the runnable sources and the transcripts they produced. There is no docs/ folder: the depth is inside the article itself.

JDK11=/path/to/jdk11 JDK17=/path/to/jdk17 ./run.sh      # regenerates output/*.txt

• src/ compiles and runs unchanged on the JDK named in each output header.
• broken/ fails to compile on purpose; the compiler's own message is committed in output/.
• output/ is real captured output, regenerated by run.sh.

Tested on: Temurin 17.0.20.1, plus 11.0.32.1 for the strong-encapsulation comparison.
