Implement the following methods in Java:

a. A method named MergeFileswith the following signature that gets two file names and write the content of the first file (sourceFile) into the beginning of the second file (destinationFile. For example, if sourceFile contains “Hello ” and destinationFile contains “World!”, this method must keep sourceFile as it is, but replace the content of the second file by “Hello World!”.public static voidMergeFiles(String sourceFile, String destinationFile)

b. A recursive method with the following signature that gets an Arraylist of Strings and starting from the second node, deletes all alternate nodes of it. The method returns an Arraylist containingthe shortened listin reverseorderas the output.public static ArrayList<String> RecursiveReverseDeleteAlt (ArrayList<String> list)

Use Java programming to implement the following: Implement the following methods in the UnorderedList class for managing a singly linked list that cannot contain duplicates. Default constructor Create an empty list i.e., head is null. boolean insert(int data) Insert the given data into the end of the list. If the insertion is successful, the function returns true; otherwise, returns false. boolean delete(int data) Delete the node that contains the given data from the list. If the deletion is successful, the...

JAVA the task is to implement the missing methods in the LinkedIntSet class. Each method you must write has comments describing how it should behave. You may not add any new fields to the LinkedIntSet class and you may only add new code inside the bodies of the 5 methods you are asked to write. You may also write new private helper methods. However, you may not change any method headers, you may not change any code outside of the...

You shall implement six static methods in a class named BasicBioinformatics. Each of the methods will perform some analysis of data considered to be DNA. DNA shall be represented arrays of chars containing only the characters A, C, G and T. In addition to the six methods you will implement, six other methods exist in the class, which use Strings instead of char arrays to represent DNA. These other methods simply invoke the methods you are to implement, so all...
