В файле filename + ".in" в первой строке — число тестов, со следующей строки — тесты в формате <вход>\n<ответ>. После этого нужно добавить строки accept: AC reject: RJ blank: _ start: S В конце — описание машины Тьюринга. Функцию check, если хочется, можно написать.
import java.io.*;
import java.util.*;
public class InterpretatorMulti {
int tapesCount;
String blank;
State accept;
State reject;
State start;
Map<String, State> states;
