- All Implemented Interfaces:
- Function
- public final class Translate
- extends AbstractFunction
returns the first argument string with occurrences of characters in the second argument
string replaced by the character at the corresponding position in the third argument string.
For example, translate("bar","abc","ABC") returns the string BAr. If there is a character in
the second argument string with no character at a corresponding position in the third argument
string (because the second argument string is longer than the third argument string), then
occurrences of that character in the first argument string are removed. For example,
translate("--aaa--","abc-","ABC") returns "AAA". If a character occurs more than once in the
second argument string, then the first occurrence determines the replacement character. If the
third argument string is longer than the second argument string, then excess characters are
ignored.
