Examples of java.io.Console.printf()

java.io.Console.printf()
A convenience method to write a formatted string to this console's output stream using the specified format string and arguments.
An invocation of this method of the form con.printf(format, args) behaves in exactly the same way as the invocation of
```
con.format(format, args)
```
. @param format A format string as described in Format string syntax. @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 number of arguments is variable and may be zero. The maximum number of arguments is limited by the maximum dimension of a Java array as defined by The Java™ Virtual Machine Specification. The behaviour on a null argument depends on the conversion. @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. @return This console
