String name = "Alan";
System.out.printf(STR."Hello, my name is \{name}");
Error:
Macbook % java --enable-preview --source Main.java
error: no path for source file
Macbook % java --enable-preview Main.java
If you make use of the preview feature from a Java JDK version say JDK 17 or 21, you will need to pass in both the option --enable-preview and --source when you compline (javac) or run (java) a Java program from Terminal or else you will get the error as above.PE|
Fix:
Here I am making use of the Java JDK 21, so I need to pass 21 after --source flag to make the code work.
% java --enable-preview --source 21 Main.java
Note: Main.java uses preview features of Java SE 21.
Note: Recompile with -Xlint:preview for details.
Hello, my name is Alan
Note, if you provide any other JDK versions ay 17, and you have 21, you will get the below error.
% java --enable-preview --source 17 Main.java
error: invalid source release 17 with --enable-preview
(preview language features are only supported for release 21)
error: compilation failed
