- Given a class Square with an instance variable width, provide a recursive getArea method. Construct a square whose width is one less than the original and call its getArea method. Make a resource class that contains all of the methods and make a driver class in a separate file, and the driver class only needs to call those methods. The driver class needs to have only 5 lines of code. The code will need to be written in Java. Please help me with exactly what I asked for helpJava allows for methods to be chained together. Consider the following message from the captain of a pirate ship: String msg1 = " Maroon the First Mate with a flagon of water and a pistol! "; We want to change the message to read the message msg1: String msg2= “Maroon the Quartermaster with a flagon of water.” Three changes need to be made to adjust the string as desired: Trim the leading and trailing whitespace. Replace the substring First Mate with Quartermaster. Remove "and a pistol!" Add a period at the end of the sentence. A “chaining1” method which will apply in sequence 4 operations to perform the above. We will use the trim, replace, and substring methods, in this order. Thus the chaining1 method will receive a string msg1 and return a string msg2. Make sure msg2 is printed. A “chaining2” method which will apply the 4 operations above in one single statement. Thus the chaining2 method will receive a string msg1 and return as string msg2. Make sure msg2 is printedJava allows for methods to be chained together.

Create a class SubstitutionCipher that implements the interface MessageDecoder as described above. The constructorshould have one parameter called shift. Define the method decode so that each letter is shifted by the value in the shif. For example, if shift is 3, a will be replaced by d, b will be replaced bt e, c will be replaced by f, and so on. Hint: You may wish to define a private methodthat shifts a single character. Create a class ShuffleCipher that implements the interface MessageDecoder. The constructor should haveone parameter called n. Define the method decode so that the message is shuffledn times.To perform one shuffle, split the message in half and then take the charactersfrom each half alternatively. For example, if the messsage is "abcdefghi", the halves are "abcde" and "fghi". The shuffled…Write code for the InternetThing class to complete: a.

Package your programme as a static method count(), which accepts N as an argument and returns the number of connections, and a main() function, which takes N from the command line, calls count(), and prints the result.1) Implement a class Moth that models a moth flying along a straight line. The moth hasa position, which is the distance from a fixed origin. When the moth moves toward apoint of light, its new position is halfway between its old position and the position ofthe light source. Find the instance variable(s), define and implement the constructor(s), then supplythe following methods:- public void moveToLight(double lightPosition) - public double getPosition()2) Document your class, generate Javadoc documentation and produce a test program ‘MothTester’that construct a moth, move it toward a couple of light sources, and check that the moth’s positionis as expected. 3) Add a comment to your class Moth that explains how you can make the Moth immobile after 10moves.

This class defines a method called contains(), which takes as parameters an integer array a, an integer x, an int called start, as well as an int called end, and returns a boolean which is true if and only if x occurs in a at a position which is greater than or equal to start, and less than end. You must validate that start is less than or equal to end, and that both start and end are greater than or equal to 0, and less than or equal to a.length.
