question: public boolean isIncompleteNumericalRun ( String pin ) { final int len = pin . length ( ) ; int consecutive = 0 ; char last = pin . charAt ( 0 ) ; for ( int i = 1 ; i < len ; i ++ ) { final char c = pin . charAt ( i ) ; if ( last == c ) { consecutive ++ ; } else { consecutive = 0 ; } last = c ; if ( consecutive >= 2 ) { return true ; } } return false ; }
target:  Tests the string to see if it contains a partial numeric run. Eg. 3000, 5553
