question: public static Vector padLeft ( Collection strings ) { Vector v = new Vector ( ) ; int length = maxLength ( strings ) ; for ( Iterator i = strings . iterator ( ) ; i . hasNext ( ) ; ) { String string = ( String ) i . next ( ) ; v . add ( padLeft ( string , length ) ) ; } return v ; }
target:  Returns a collection of strings based on the given collection but with all strings padded on the left to the length of the longest one.
