### Question:
SystemLogTree extends FormatterPriorityTree { @Override protected void log(int priority, String tag, @NotNull String message, Throwable t) { if (skipLog(priority, tag, message, t)) { return; } System.out.print(format(priority, tag, message)); if (t != null) { t.printStackTrace(); } } SystemLogTree();  SystemLogTree(int priority);   }### Answer:
@Test public void log() { SystemLogTree tree = new SystemLogTree(); tree.setFormatter(LogcatFormatter.INSTANCE); LogcatFormatter.INSTANCE.setTimeStamper(new TimeStamper("MM-dd HH:mm:ss:SSS", TimeZone.getTimeZone("GMT+2"))); }
