Java Programming: Below is the lexer, shank and token files along with the shank.txt file. The shank file is the main method file. The lexer must break up the input text stream into lexemes and return a token object for each one in the shank.txt file. Make sure to fix the errors in the lexer.java file and show the complete code for lexer.java.There must be no error in the code at all. Run the whole code and show the output which the shank.txt must be printed out in the terminal. Attached is the rubric.

Class TextEdit
In text editing class. Its constructor it receives a string. The string will be stored in a field called initialValue using proper setter methods and proper documentation for Each of the methods.
This class also contains another String field called: ”mixedResult” which is only defined globally and will be initialized using a method in the future in the main class namely the mix method.
The public String toToken() method is a method that will use the initialValue field and it for the letter ’p’ or the letter ’A’. If it finds the letter, every element on the left side of the found letter will be stored in another string and returned. Example: If the initialValue was: ”This is a possible resource allocation”. The returning String will be: ”possible resource allocation”.
Use control statements here iterate through the string using a counter control…
private LocalDate date
private Doctor doctor,
private boolean status
private String appointmentNumber.
What to do
1. (5) Provide the following:
• A fully parameterized constructor.
Setter and getter for all attributes.
2. (5) Add a toString method.
It should return a String similar to the following (Note: you should only add the doctor's
name):
Expected Output:
Date: 2022-04-01
Doctor Name: Dr. Ahmed

- Part I: PrintVertical.java Write a program that will prompt the user to enter a sentence (string data), read that sentence into your program as a single string, and then finally process the string by calling the method specified below (vertical). You must process the sentence by calling the method rather than processing the string directly in your main method. Write a void method, vertical, which receives a string as a parameter and prints each letter of the string to the screen on separate lines.

- Define a class called StringFormatter. The purpose of an object of this class is to store a string variable (you may use the C++ string type or a char array). An object of this class can be created by calling a constructor that accepts one string argument. The string to be passed as argument will be a long line of text, such as “The world is indeed full of peril and in it there are many dark places. But still there is much that is fair. And though in all lands, love is now mingled with grief, it still grows, perhaps, the greater.” The object will also have a function called printRightAligned() which accepts one integer argument n. The value of the argument represents the maximum number of characters that can be displayed on a line. This function displays the string stored in the object’s attribute on the screen, right aligned and with no more than n characters per line. Similarly, there should be a function called printLeftAlgigned() which displays the text left aligned, again, with no…arrow_forwardIn some circumstances, a class is reliant on itself. That is, one class's object interacts with another class's object. To accomplish this, a method of the class may accept an object of the same class as a parameter.The String class's concat function is an example of this situation. The method is called by one String object and receives another String object as an argument. Here's an illustration:str3 is equal to str1.concat(str2);The method's String object (str1) appends its characters to those of the String supplied as a parameter (str2). As a consequence, a new String object is returned and saved as str3. Create Java code to implement the conditions given.arrow_forwardA class may occasionally be dependent upon itself. In other words, an object of one class engages in communication with an object of the same class. To do this, a method of the class can take an object of the same class as a parameter.An illustration of this scenario is the concat method of the String class. One String object calls the method, while another String object is supplied as an argument. Here's an illustration:str2 = str1.concat;The String object (str1) that executes the method adds its characters to the String (str2) that was supplied as a parameter. As a result, a fresh String object is produced and saved as str3. Write Java code to put the circumstances given into effect.arrow_forward
- A mountain climbing club maintains a record of the climbs that its members have made. Information about a climb includes the name of the mountain peak and the amount of time it took to reach the top. The information is contained in the ClimbInfo class as declared below. The ClimbingClub class maintains a list of the climbs made by members of the club. The declaration of the ClimbingClub class is shown below. You will write implementations of the addClimb method. import java.util.List; import java.util.ArrayList; class ClimbInfo { private String name; private int time; /** Creates a ClimbInfo object with name peakName and time climbTime. * * @param peakName the name of the mountain peak * @param climbTime the number of minutes taken to complete the climb */ public ClimbInfo(String peakName, int climbTime) { name = peakName; time = climbTime; } /** @return the name of the mountain peak */ public String getName() { return name; } /** @return the number of minutes…arrow_forwardDescription is " A MathVector object will be passed to your method. Return its contents as a String. If you look in the file MathVector.java you'll see there is a way to output the contents of a MathVector object as a String. This makes it useful for displaying to the user. You might have noticed that there's an @override term there. That's because many objects already have a "toString()" method associated with them... because Java was designed to include them by default. Here, the override tells Java "I know, I know. You already have a toString() that you'd assign here. But it's not good enough. Here's a better one for this particular kind of object." It's a little bit like saying "Most humans have two legs. So, by default, I'll give everyone two legs. But sometimes we override that and give no legs, or just one leg to a person. And sometimes we give them four so that they can be a centaur!" To use this in a println() method, just name your object. The toString()…arrow_forwardImplement the following class. Refer to the below notes for more details.

Default is false. o minutes: private int representing the number of minutes to be invoiced (added to the bill). Default is 0. o costPerMinute: private double representing the cost of 1 minute.

- : A point in the x-y plane is represented by its x-coordinate and y-coordinate. Design a class, pointType, that can store and process a point in the x-y plane.
