### Question:
ISOFieldPackager { public ISOComponent createComponent(int fieldNumber) { return new ISOField (fieldNumber); } ISOFieldPackager();  ISOFieldPackager(int len, String description); String getDescription(); void setDescription(String description); int getLength(); void setLength(int len); void setPad(boolean pad); void setTrim(boolean trim); abstract int getMaxPackedLength(); ISOComponent createComponent(int fieldNumber); abstract byte[] pack(ISOComponent c); abstract int unpack(ISOComponent c, byte[] b, int offset); void unpack(ISOComponent c, InputStream in); void pack(ISOComponent c, ObjectOutput out);  }### Answer:
@Test public void testCreateComponent() throws Throwable { ISOField result = (ISOField) new IFB_AMOUNT().createComponent(100); assertNotNull(result); assertTrue(true, "Test completed without Exception"); }
