#GettingToKnowIntelliJ
IntelliJ IDEA can let us know about problems in the classes that extend sealed classes (a preview feature in #Java 16), and suggest solutions.
#JDK16 #2021.1 #GettingToKnowIntelliJ
Sealed classes (a preview feature in #Java 16) are a way to take control of inheritance. With a sealed class like this one, IntelliJ IDEA will tell us we need to "permit" the child class, and automatically make changes if it can.
#JDK16 #2021.1 #GettingToKnowIntelliJ
If you want to use preview features in the latest versions of #Java in IntelliJ IDEA, you need to set the language level to "Preview"
#JDK16 #2021.1 #GettingToKnowIntelliJ
We've just launched the first edition of our #IntelliJ IDEA Guide! We hope this will serve as a central location for all your favourite tips and tricks. Check it out and and let us know what you think! #GettingToKnowIntelliJ

#JDK16 has marked the wrapper class constructors for removal, so you'll see these with a red strikethrough in IntelliJ IDEA. The IDE can automatically replace these with a better approach.
#JDK16 #GettingToKnowIntelliJ
IntelliJ IDEA can find places in our code that can use Pattern Matching for instanceof. There were some changes to this feature in #JDK16 which are fully catered for in IntelliJ IDEA 2021.1.
#JDK16 #2021.1 #GettingToKnowIntelliJ
If we decide that maybe a record should be a full Java class after all, we can get IntelliJ IDEA to automatically convert a record into a Java class.
#JDK16 #2021.1 #GettingToKnowIntelliJ
IntelliJ IDEA can spot classes that can be converted to records. The fields will be become record components, and the constructor and accessors will be removed.
#JDK16 #2021.1 #GettingToKnowIntelliJ
Create a new record from the "New Java Class" dialog: type the name of the record and select the Record type.
#JDK16 #2021.1 #GettingToKnowIntelliJ
#IntelliJTopShortcut: You can use ⌘⇧N on macOS, or Ctrl+Alt+Shift+Ins to copy some selected text from a file into a new scratch file of the same type.
#GettingToKnowIntelliJ
#IntelliJTopShortcut: You can use ⌘ + numbers 1-9 on macOS, or Alt + numbers 1-9 on Windows/Linux to toggle the Tool windows on, and off.
#GettingToKnowIntelliJ
#IntelliJTopShortcut: If we have a long parameter list in Kotlin, we can use ⌥⏎ on macOS, or Alt+Enter on Windows/Linux, to put each parameter on a separate line. You can use the same shortcuts to put parameters into one line as well.
#GettingToKnowIntelliJ
#IntelliJTopShortcut: You can extend the selection by scope with ⌥↑ on macOS, or Ctrl+W on Windows/Linux. You can shrink the selection by scope with ⌥↓ on macOS, or Ctrl+Shift+W on Windows/Linux.
#GettingToKnowIntelliJ
#IntelliJTopShortcut: When a Kotlin expression requires us to cover all the possible options for a parameter, we can use ⌥⏎ on macOS, or Alt+Enter on Windows/Linux, to generate all the branches automatically.
#GettingToKnowIntelliJ
#IntelliJTopShortcut: You can use ⌥⏎ on macOS, or Alt+Enter on Windows/Linux to show context actions for your selection and then edit the code style.
#GettingToKnowIntelliJ
#IntelliJTopShortcut: You can select code by scope and then use ⌥⌘T on macOS, or Ctrl+Alt+T on Windows/Linux to create an editor fold. These are useful to minimise code while you're working on other code. You can always maximise them later.
#GettingToKnowIntelliJ
#IntelliJTopShortcut: We can use ⌥⏎ on macOS, or Alt+Enter on Windows/Linux, before the first parameter to add names to call arguments. You can use the same shortcut again before one argument to add names from that parameter, or just for that parameter.
