Examples of java.io.PrintWriter.format()

java.io.PrintWriter.format()
Writes a string formatted by an intermediate Formatter to this writer using the given format string and arguments. A call to this method flushes the buffered output, if the automatic flushing is enabled.
The method uses the default for the current JVM instance locale, as if it is specified by the Locale.getDefault() call. @param format A format string. @param args The arguments list. If there are more arguments than those specified by the format string, then the additional arguments are ignored. @return This writer. @throws IllegalFormatException If the format string is illegal or incompatible with the arguments or the arguments are less than those required by the format string or any other illegal situation. @throws NullPointerException If the given format is null.
