We also want to highlight two improvements to tooling support for new Java versions: Source fixing (cleanups that fix incorrect code, but may change execution).To help find them, the Java Cleanup configuration page has been reorganized and three new tabs were added: In addition, more than 60 cleanups and quick fixes have been added since the 2020-06 IDE release. When completing a method call, the Java Editor now inserts the best-guessed parameters from available variables and parameters, rather than simply inserting the method parameter names. This is helpful for developers who can remember the subwords of a class name, but not the full name. The Java Editor now supports substring and subword matches for types when performing code completion. There are a number of major improvements in the Eclipse JDT, including better code completion, new cleanups and quick fixes, support for new Java versions, and debugger enhancements.
