I solve an example from the textbook. Created a file Puzzle4.java, in it main class. I'm trying to compile (there are most likely errors in the code, I wanted to see what the compiler would write).

$ ls Mix4.class Mix4.java Puzzle4.java README.md test.txt $ javac Puzzle4.java $ ls Mix4.class Mix4.java Puzzle4.java README.md test.txt

No errors were output to the terminal. In the folder there is another example Mix4.java, which was successfully compiled and launched. Versions of javac and java are the same:

 $ java -version java version "1.8.0_101" Java(TM) SE Runtime Environment (build 1.8.0_101-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode) $ javac -version javac 1.8.0_101

What should I do to make the compiler display information about errors in the code?

    And where did you get that there are errors in the code if the compiler did not give you anything? If there is, for example, RuntimeException , then the compiler will not give you anything. just need to run - Chubatiy
  • Give the code in which the compiler should, in your opinion, produce an error. - GreyGoblin
  • @GreyGoblin helped, opened the file, and there it is empty. As usual, the elephant could not make out (did not save the code in the file). - Hev

Thanks @GreyGoblin, only after his request to show the code I realized that I did not save the file and it was empty. After editing the file, the compiler produces errors, but this was what I needed, so the issue is resolved.
