Examples of java.io.Console.readPassword()

java.io.Console.readPassword()
Provides a formatted prompt, then reads a password or passphrase from the console with echoing disabled. @param fmt A format string as described in Format string syntax for the prompt text. @param args Arguments referenced by the format specifiers in the format string. If there are more arguments than format specifiers, the extra arguments are ignored. The maximum number of arguments is limited by the maximum dimension of a Java array as defined by The Java™ Virtual Machine Specification. @throws IllegalFormatException If a format string contains an illegal syntax, a format specifier that is incompatible with the given arguments, insufficient arguments given the format string, or other illegal conditions. For specification of all possible formatting errors, see the Details section of the formatter class specification. @throws IOError If an I/O error occurs. @return A character array containing the password or passphrase readfrom the console, not including any line-termination characters, or null if an end of stream has been reached.
