### Question:
DefaultLogFormatter implements Formatter { @Override public String format(int priority, String tag, @NotNull String message) { String prio = prioPrefixes.get(priority); if (prio == null) { prio = ""; } return prio + (tag == null ? "" : tag + " : ") + message + "\n"; } private  DefaultLogFormatter(); @Override String format(int priority, String tag, @NotNull String message); static final DefaultLogFormatter INSTANCE; }### Answer:
@Test public void test() { assertThat(defaultLogFormatter.format(1, "tag", "message"), is("tag : message\n")); assertThat(defaultLogFormatter.format(2, "tag", "message"), is("V/tag : message\n")); assertThat(defaultLogFormatter.format(3, "tag", "message"), is("D/tag : message\n")); assertThat(defaultLogFormatter.format(4, "tag", "message"), is("I/tag : message\n")); assertThat(defaultLogFormatter.format(5, "tag", "message"), is("W/tag : message\n")); assertThat(defaultLogFormatter.format(6, "tag", "message"), is("E/tag : message\n")); assertThat(defaultLogFormatter.format(7, "tag", "message"), is("WTF/tag : message\n")); assertThat(defaultLogFormatter.format(8, "tag", "message"), is("tag : message\n")); }
