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