question: public boolean shExpMatch ( String str , String shexp ) { StringTokenizer tokenizer = new StringTokenizer ( shexp , "*" ) ; int startPos = 0 ; while ( tokenizer . hasMoreTokens ( ) ) { String token = tokenizer . nextToken ( ) ; int temp = str . indexOf ( token , startPos ) ; if ( startPos == 0 && ! shexp . startsWith ( "*" ) && temp != 0 ) { return false ; } if ( ! tokenizer . hasMoreTokens ( ) && ! shexp . endsWith ( "*" ) && ! str . endsWith ( token ) ) { return false ; } if ( temp == - 1 ) { return false ; } else { startPos = temp + token . length ( ) ; } } return true ; }
target:  Returns true if the string matches the specified shell expression. Actually, currently the patterns are shell expressions, not regular expressions.
