20. What is the difference between a doubly-linked list and a singly-linked list? (A) A doubly-linked list can hold twice as much data as a singly-linked list. (B) A doubly-linked list is a chain of lists, while a singly-linked list is a chain of nodes. (C) Nodes in the doubly-linked list have a reference to the previous node in the list, as well as the next node. (D) The doubly-linked list has a reference to the last node in the list, as well as the first node, while the singly-linked list has only one such reference. (E) It is easier to print a singly-linked list.

Hint: To calculate the distance between two points, you can use a method defined in the appendix in the Maputilities class . Write a method findNearest Station which takes as input a double x and a double y ad the Metrostation which is nearest to the x and y. To do this, it should leather all the Metrostations of all the Metrotines inside of this lines and find the Metro Station that is the smallest distance away. You can use the same appendix method as in the precis i on You may assume that there is a leadine MetroLine defined in the property lines. You may also assume that every MetroLine in lines has at least one Metrostation in Hint There is no method such as getAll Station defined a Metrotine ohjeet. This is since providing this method would rewal a lot about the implementation of the Metrolines and would differ depending on the kind of collectice you are using to store it. However, you can simulate this art of method by using the get PirstStop () and get Next Stop () methods to access every entry of the AmyList. Remember the condition that will cause getNext Stop (to be null • A method qet Neighboringstations which takes input a Metrostation station and re- turns an ArrayList The Arrayut Metrostation whild consist of all nephring stations to station possibly many if the station in ce may lines).

9. Write a method with the following header public static void replace (String oldFile, string newfile, char oldChar, char newChar) throws IOException This method opens the file whose name is given by the String parameter oldFile (the input file) for reading, and opens the file whose name is given by the string parameter newlile (the output file) for writing. It then reads every lime in the input file. For each line, it creates a new line identical to the original line, creept for the fact that all occurrences of char oldchar in the original String have been replaced by occurrences of char newchar in the new line. When the new line has been properly created, it write it to the output file. Once all the lines in the input file have been read and a corresponding line has been written to the output file, the method clases both files. Additional notes: • You MAY assume that none of the parameters this method accepts are null; in other words, your method does not have to handle the case where one or more of the parameters are null. You MAY assume that all the 10-related classes have already heen imported properly . Finally, because the replace() method is specified to throw an exception object of type TORxception, you MAY assume that I/O related problems will occur while reading from the input file or writing to the output file. In other words, your method DOES NOT have to check that no such problems occur, and DOES NOT have to manage Texceptions using try-catch blocks.
