printf - Exception in thread "main" java.util.UnknownFormatConversionException: Conversion = '_' -

the problem conversion = "_". source code here. tried read txt , ok! code "tokenize" words , ok too. when seek save in txt error.

but if delete "__" save don't want delete "_"!

this programme used tokenize words.

i want know should in line. or can run project without exception.

exception in thread "main" java.util.unknownformatconversionexception: conversion = '_' @ cugru.test.main(test.java:81)

here code:

the method printf() not same println(). used formatted output. first parameter string formats characters. example:

system.out.printf( "%2d %2d%n", x, y );

but used thing wanted print first argument. method thinks format string, , looks parts begin %. have % in string, after there _. not legal format, exception.

you wanted utilize println() method. using eliminate exception.
