question: private String formatType ( Object typeRep ) { StringTokenizer tokenizer = new StringTokenizer ( typeRep . toString ( ) , "()<>[], " , true ) ; StringBuilder sb = new StringBuilder ( ) ; while ( tokenizer . hasMoreTokens ( ) ) { String token = tokenizer . nextToken ( ) ; if ( token . length ( ) == 1 || token . lastIndexOf ( '.' ) == - 1 ) sb . append ( token ) ; else { int index = token . lastIndexOf ( '.' ) ; sb . append ( token . substring ( index + 1 ) ) ; } } return sb . toString ( ) ; }
target:  outputs the simple name of the type
