This is class for constants of a built-in sort. It defines constants of built-in sorts, such as integers, floating-point numbers, booleans, strings, . It is an abstract class because it does not itself carry the value of such an constant. This is done by a concrete subclass of Constant, depending on the type of value of the constant. Here are the concrete subclasses of Constant:
  1. IntegerConstant, the class of objects carrying an integer value (i.e., an int);
  2. CharConstant, the class of objects carrying a character value (i.e., a char);
  3. FloatConstant, the class of objects carrying a double-precision floating point value (i.e., a double);
  4. StringConstant, the class of objects carrying a string value;
  5. BooleanConstant, the class of objects carrying a boolean value (i.e., true or false);
