### Question:
CardHolder implements Cloneable, Serializable, Loggeable { public void dump (PrintStream p, String indent) { p.print (indent + "<CardHolder"); if (hasTrack1()) p.print (" trk1=\"true\""); if (hasTrack2()) p.print (" trk2=\"true\""); if (hasSecurityCode()) p.print (" sec=\"true\""); if (isExpired()) p.print (" expired=\"true\""); p.println (">"); p.println (indent + " " + "<pan>" +pan +"</pan>"); p.println (indent + " " + "<exp>" +exp +"</exp>"); p.println (indent + "</CardHolder>"); } CardHolder();  CardHolder(String track2);  CardHolder(String pan, String exp);  CardHolder(ISOMsg m); void parseTrack2(String s); void setTrack1(String track1); String getTrack1(); boolean hasTrack1(); String getNameOnCard(); String getTrack2(); boolean hasTrack2(); void setSecurityCode(String securityCode); String getSecurityCode(); boolean hasSecurityCode(); @SuppressWarnings("unused") String getTrailler(); @SuppressWarnings("unused") void setTrailler(String trailer); String getTrailer(); void setTrailer(String trailer); void setPAN(String pan); String getPAN(); String getBIN(); void setEXP(String exp); String getEXP(); boolean isExpired(); boolean isExpired(Date currentDate); boolean isValidCRC(); static boolean isValidCRC(String p); void dump(PrintStream p, String indent); String getServiceCode(); boolean seemsManualEntry(); @Override int hashCode(); @Override boolean equals(Object obj);  }### Answer:
@Test public void testDump() throws Throwable { CardHolder cardHolder = new CardHolder("testCardHolderPan", "4Cha"); cardHolder.setSecurityCode("testCardHolderSecurityCode"); PrintStream p = new PrintStream(new ByteArrayOutputStream(), true, "UTF-8"); cardHolder.dump(p, "testCardHolderIndent"); assertTrue(true, "Test completed without Exception"); }
@Test public void testDump6() throws Throwable { PrintStream p = new PrintStream(new ByteArrayOutputStream(), true, "UTF-8"); new CardHolder("testCardHolderPan", "4Cha").dump(p, "testCardHolderIndent"); assertTrue(true, "Test completed without Exception"); }
@Test public void testDumpThrowsNullPointerException() throws Throwable { try { new CardHolder("k'X9|DH:!;uQ<kG8!P?- ,\"Y!u`r;jB^)>3AbS9,").dump(null, "testCardHolderIndent"); fail("Expected NullPointerException to be thrown"); } catch (NullPointerException ex) { if (isJavaVersionAtMost(JAVA_14)) { assertNull(ex.getMessage(), "ex.getMessage()"); } else { assertEquals("Cannot invoke \"java.io.PrintStream.print(String)\" because \"p\" is null", ex.getMessage(), "ex.getMessage()"); } } }
