### Question:
CharacterProperties { public byte toByteCode() { return code; } private  CharacterProperties(byte code);  CharacterProperties(boolean isAlpha, boolean isDigit,
            boolean isUpper, boolean isLower, boolean isPunctuation); static CharacterProperties forByteCode(byte code); static CharacterProperties forHexString(String hexString); static CharacterProperties forCharacter(char c); static CharacterProperties forString(String cs); boolean isAlpha(); boolean isLower(); boolean isUpper(); boolean isDigit(); boolean isPunctuation(); byte toByteCode(); String toHexString(); @Override String toString(); @Override int hashCode(); @Override boolean equals(Object obj);  }### Answer:
@Test public void testToByteCode() { assertEquals(semicolon.toByteCode(), (byte) 16); assertEquals(b.toByteCode(), (byte) 3); assertEquals(W.toByteCode(), (byte) 5); assertEquals(digit7.toByteCode(), (byte) 8); assertEquals(equalSign.toByteCode(), (byte) 0); }
