Can you help me with this assignment in Java Programming

1 Static Generic Methods Most of the methods we write in class won't be static, but that's no reason not to learn how to do that. Java makes writing generic methods look intimidating, but in reality, it's not so bad. I'll walk you through how to do it by showing what we want to do, hitting an error, and then showing you how to resolve the error. Suppose we want to write a method called in, which given a List and an item, checks to see if the List contains that item. I We don't know what type the item will, nor do we know what kind of stuff the List will be holding, as that will change from one program to another, and we want this method to be able to be used in any kind of context. That means we want it to be generic. However, if we write //this is an error public static boolean in (List list, E item){ We get "E cannot be resolved to a type" as an error. This happens because Java doesn't know that you want to use E as the symbol for generics for this method. We can fix this by adding a in between static and our return type, like so: public static boolean in (List list, E item) { The big difference here between a class that uses a generic, like ArrayList, and the static methods you write here is that the generic type only exists for the method. 1.1 When Not to Use The Above You do not have to have method methods generic when we know what types we are using. For instance, if we know we are dealing with a list of integers (List), we don't have to write anything generic in. We just write: public static returnType myMethod (List list){ For each method, ask yourself Does this method need to work on a List of any type, or just a single type?" If any type, you need to make a generic method. If a single type, then you don't need to use a generic in that method. lThis exists as an instance method under a different name within any List, but let's pretend it doesn't. 2 The Methods For each of the following, create a static method with the appropriate inputs and outputs. Call each of them in the main method. 2.1 Uniqueness Write a method called unique () which takes in a List and returns true if all the items in the List are unique. All the items are unique if none of them are the same!2 Return false otherwise. 2.2 All Multiples Write a method named allMultiples() which takes in a List of integers and an int. The method returns a new List of integers which contains all of the numbers from the input list which are multiples of the given int. For example, if the List is [1, 25, 2,5, 30, 19, 57, 2, 25) and 5 was provided, the new list should contain (25,5, 30,25). 2.3 All Strings of Size Write a method named aliStringsOfSize () which takes in a List and an int length. The method returns a new List which con- tains all the Strings from the original list that are length characters long. For example, if the inputs are ["I", "like", "to", "eat", "eat", "eat", "apples", "and", "bananas") and 3, the new list is ["eat", "eat", "eat", "and"]. 2.4 is Permutation Write a method called isPermutaion() which takes in two List objects which contain the same types. It returns true if the Lists are permutations of each other and false if not. Two lists are permutations if they contain the same elements, including the same number of duplicates, but they don't have to contain the elements in the same order. For example, [1,2, 4] and [2,1,4] are permutations of each other. 2.5 String To List of Words Write a method called stringToListOf Words () which takes in a String con- verts it into a list of words. We assumes that each word in the input string is separated by whitespace 2 Use the equals() method. 3 The split() method of String can split an input up along a provided special string called a regular expression or regex. A regex is much like a code for pattern, and split() will match anything in that pattern. The regex "\\s+" matches any amount of whitespace. If our input String is "Hello, world!", then the output should be ["Hello,", "world!"). For extra credit, sanitize the String, cleaning it up so that we re- move the punctuation and other extraneous characters such that the output in the above example would become ["Hello", "world"] This method returns List. 2.6 Remove All Instances Write a method called removeAllInstances () which takes in a List and item!. The method then proceeds to remove each item in the list that matches the given item. For example, if the method is passed the List (1, 4, 5, 6, 5, 5, 2] and the Integer 5, the method removes all 5's from the List. The List then becomes [1, 4, 6, 2]. It should return nothing, since the changes the List it was provided. *
