Writing to disk without using java.io

Question

Suppose the use of java.io has been blocked. What are some alternative ways of writing, say a simple "Hello World!" text file to disk, using Java/Groovy language features?

Answer 1

If only java.io has been blocked (you said java.io imports are blocked), you can use the java.nio to write to files.

Look at the central Files class. In java.nio files/folders are represented with java.nio.Path objects which is also part of the java.nio package (and not java.io).

Example writing "Hello World!" into a text file to the disk:

Files.write(Paths.get("/your/folder/text.txt"),
    "Hello World!".getBytes(StandardCharsets.UTF_8));

// Or
Files.write(Paths.get("/your/folder/text.txt"),
    Arrays.asList("Hello World!"), StandardCharsets.UTF_8);
