### Question:
CharacterProperties { public static CharacterProperties forCharacter(char c) { return forString("" + c); } 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 testForCharacter() { assertEquals(CharacterProperties.forCharacter(';'), semicolon); assertEquals(CharacterProperties.forCharacter('b'), b); assertEquals(CharacterProperties.forCharacter('W'), W); assertEquals(CharacterProperties.forCharacter('7'), digit7); assertEquals(CharacterProperties.forCharacter('='), equalSign); assertEquals(CharacterProperties.forCharacter('ß'), sharpS); assertEquals(CharacterProperties.forCharacter('Ä'), umlautA); }
