question: int findEndText ( String source , int ofs ) { for ( int i = ofs ; i < source . length ( ) ; i ++ ) { if ( isAlpha ( source . charAt ( i ) ) == false && isNumeric ( source . charAt ( i ) ) == false ) { return i ; } } return - 1 ; }
target:  Attempt to find the end of a field if the length is not known.
