You can output a
char
value using a
println( )
statement. For example, this line outputs
the value in
ch
:
Since
char
is an unsigned 16-bit type, it is possible to perform various arithmetic ma-
nipulations on a
char
variable. For example, consider the following program:
The output generated by this program is shown here:
In the program,
ch
is first given the value X. Next,
ch
is incremented. This results in
ch
containing Y, the next character in the ASCII (and Unicode) sequence. Next,
ch
is assigned
the value 90, which is the ASCII (and Unicode) value that corresponds to the letter Z. Since
the ASCII character set occupies the first 127 values in the Unicode character set, all the
“old tricks” that you may have used with characters in other languages will work in Java,
too.
