Read this blog post: Get Rid of Java Static Loggers

Logger is a convenient static wrapper of slf4j (don't forget to include one of SLF4J Bindings into the project):

import com.jcabi.log.Logger;
class Foo {
  void bar(int value) {
    Logger.debug(this, "method #bar(%d) was called", value);
  }
}

Besides standard %s placeholders inside the format string, you can use other custom ones, which help formatting common values faster:

• %[file]s --- absolute file name ➜ file name relative to current directory
• %[text]s --- any string ➜ pretty looking text, short enough, and escaped
• %[exception]s --- Exception ➜ stacktrace
• %[list]s --- Iterable ➜ pretty formatted list, in one line
• %[size]s --- size in bytes ➜ Kb, Mb, Gb, Tb, and so on
• %[ms]s --- milliseconds ➜ ms, sec, min, hours, etc.
• %[nano]s --- nanoseconds ➜ µs, ms, sec, min, hours, etc.
• %[type]s --- Class<?> ➜ name of it
• %[secret]s --- any string ➜ stars
• %[dom]s --- org.w3c.domDocument ➜ pretty printed/formatted XML

You are welcome to suggest your own "decors".
