Chapter 3. Java 9 Language Enhancements

In the previous chapter, we gained insight into some exciting new features contained in Java 9. Our focus was on javac, the JDK libraries, and test suites. We learned about memory management improvements including memory allocation, heap optimizations, and enhanced garbage collection. We also covered changes to the compilation process, type testing, annotations, and runtime compiler tests.

This chapter covers some changes in Java 9 that impact variable handlers, depreciation warnings, improvements on Project Coin changes implemented in Java 7, and import statement processing. These represent changes to the Java language itself.

The topics we will cover here are:

  • Variable handlers
  • Import statement depreciation warnings
  • Project Coin
  • Import statement processing
