Get content of a file in Java

Question

I want to get the version of Linux using Java code. In different Linux distributions I have file with diffrent name.

/etc/*-release

How I can get every file content which ends with -release?

Answer 1

You can use File.listFiles(FilenameFilter)

    File f = new File("/etc/");
    File[] allReleaseFiles = f.listFiles(new FilenameFilter() {

        @Override
        public boolean accept(File dir, String name) {
            return name.endsWith("-release");
        }
    });
