### Question:
TraceFlags { public static byte getDefault() { return DEFAULT; } private  TraceFlags(); static int getHexLength(); static byte getDefault(); static boolean isSampledFromHex(CharSequence src, int srcOffset); static byte byteFromHex(CharSequence src, int srcOffset); static byte getSampled();  }### Answer:
@Test void isDefaultSampled() { assertThat(TraceFlags.getDefault()).isEqualTo((byte) 0x0); }
