class MinMaxPrimitivesBoxed { private Boolean trueValue; private Boolean falseValue; private Byte minbyteValue; private Byte maxbyteValue; private Character minCharValue; private Character maxCharValue; private Short minShortValue; private Short maxShortValue; private Integer minIntValue; private Integer maxIntValue; private Float minFloatValue; private Float maxFloatValue; private Long minLongValue; private Long maxLongValue; private Double minDoubleValue; private Double maxDoubleValue; }

• Question: What is the difference between these two classes?
