Implement a method called appendTerm: static void appendTerm (SinglyLinkedList polynomial, Double coefficient) This method should append (insert at the end) the value coefficient to polynomial. For example, appending 3.1 to polynomial already containing 6.0 0.0 ➜ -5.3 should result in the value 3.1 being added at the end: 6.0 0.0 ➜ -5.3 3.1.

// Only few methods are mentioned here //Do remaining methods to pass the test methods  /*** Removes the specified (num) of the given element from the internal ArrayList of elements. * If num <= 0, don't remove anything. * If num is too large, remove all instances of the given element from the internal ArrayList of elements.* Example:* - For a defined CustomIntegerArrayList containing the integers: 1, 2, 1, 2, 1* - Calling remove(2, 1) would remove the first 2 instances of 1 * - The CustomIntegerArrayList will then contain the integers: 2, 2, 1* - For a defined CustomIntegerArrayList containing the integers: 100, 100, 100 * - Calling remove(4, 100) would remove all instances of 100 * - The CustomIntegerArrayList will then be empty* - For a defined CustomIntegerArrayList containing the integers: 5, 5, 5, 5, 5 * - Calling remove(0, 5) would remove nothing* * @param num number of instances of element to remove * @param element to remove*/ public void remove(int num, int element) {//…

Java Complete a method calledRedundantCharacterMatch(ArrayList<Character> YourFirstName): the parameter of this method is an ArrayList<Character> whose elements are the characters in your first name (they should be in the order appear in your first name, e.g., if your first name is bob, then the ArrayList<Char> includes ‘b’, ‘o’, ‘b’.). The method will check whether there exists duplicate characters in your name and return the index of those duplicate characters. For example, when using bob as first name, it will return b: 0, 2. 2. Create an ArrayList<Character> NameExample. All the characters of your first name will appear twice in this ArrayList. For example, if your first name is bob, then NameExample will include the following element {b,o,b,b,o,b}. Then, please use NameExample as parameter for the method RedundantCharacterMatch(). If your first name is bob, the results that print in the console will be b: 0, 2, 3, 5 o: 1, 4
