Character

Synopsis

Character provides an object wrapper for a Java char primitive. The constructor initializes the wrapper with a char value, after which the object is immutable. The value associated with a Character object can be retrieved using the charValue() method.

The Character class contains several static methods that are useful for handling characters without making any assumptions about the locale in which an application is executing. The digit() method returns the integer value of a character provided that it represents a digit in a given number base, or -1 if it does not. Use the isDigit() method to test whether a given character represents a numeric digit in a given number base. The isUpperCase() and isLowerCase() methods return true if the primitive char passed to them is an upper-case or lower-case letter, respectively, while toUpperCase() and toLowerCase() convert a char to upper- or lower-case and return the result, or the original char if it has no upper- or lower-case equivalent.

The static variables Character.MIN_VALUE and Character.MAX_VALUE are char (not Character) values that represent the smallest and largest values that can be held in a char primitive.
