### Question:
LiteralInterpreter implements Interpreter { @Override public int getPackedLength(int nDataUnits) { return nDataUnits; }  @Override void interpret(String data, byte[] b, int offset); @Override String uninterpret(byte[] rawData, int offset, int length); @Override int getPackedLength(int nDataUnits); static final LiteralInterpreter INSTANCE; }### Answer:
@Test public void testGetPackedLength() { assertEquals(3, inter.getPackedLength(3)); }
