question: protected void fail ( String string ) { lastPrint = 0 ; if ( string . length ( ) > 100 ) { char [ ] data = string . toCharArray ( ) ; for ( int i = 0 ; i < data . length ; i ++ ) { char c = data [ i ] ; if ( c >= 128 || c < 32 ) { data [ i ] = ( char ) ( 'a' + ( c & 15 ) ) ; string = null ; } } if ( string == null ) { string = new String ( data ) ; } } println ( string ) ; throw new AssertionError ( string ) ; }
