Write a java code for this. Strings Read the paragraph and encrypt the content using the following rules; "The String, StringBuffer, and StringBuilder classes are defined in java.lang. Thus, they are available to all programs automatically. All are declared final, which means that none of these classes may be subclassed. This allows certain optimizations that increase performance to take place on common string operations. All three implement the CharSequence interface." RULES The words ‘the’, ‘and’, and ‘for’ should be replaced by their reverse strings in upper case letters (use predefined functions reverse() and toupper()) The first occurrence of the word ‘are’ should be replaced by ‘AREERA’ and the last occurrence of the word ‘of’ to be replaced by ‘123’.

Java Programming: Add the components needed for lexer.java according to the rubric attached.The goal is to make sure to read the shank.txt file as a series of tokens & show the shank.txt printed in console of eclipse and the image of the output is attached. Make sure the lexer has all the state machines. Make sure to have main.java. There must be no error in the lexer at all. Below is the lexer.java and token.java. Lexer.java package mypack; import java.util.ArrayList;import java.util.List;   public class Lexer {   private static final int INTEGER_STATE = 1;   private static final int DECIMAL_STATE = 2;   private static final int IDENTIFIER_STATE = 3;   private static final int ERROR_STATE = 4;    private static final char EOF = (char) -1;     private static String input;   private static int index;   private static char currentChar;    public List<Token> lex(String inputString) throws Exception {      input = inputString;      index = 0;      currentChar =…

Create a class called Student that models a student at Carleton University. A student's state consists of a name (String), id number (int) and a list of grades (array of double). Your class must have a constructor that has three input parameters (name, id and grade list) and sets the initial state for the object. Include a toString() method that returns a useful string representation of a student object. The string representation should contain the student's name, ID number, and the number of grades they have recorded (so NOT include all the grades). Include a gradesInRange(double lower, double upper) method that returns the number of grades that this student has that are in the range [lower,upper]. That is, the it returns the number of grades that are greater than or equal to lower and less than or equal to upper. Example Usage: double[] grades {81.2, 93.2, 76,2, 84.6, 63.11, 79.8}; Student s new Student("cat", 100123987, grades); s.gradesInRange (80,100); int num_grades_A // assert…

The following is the specification for the constructor of a EmailFolder class: /*** Creates a new EmailFolder with the given label** @precondition label != null AND !label.isEmpty()* @postcondition getLabel()==label*/public EmailFolder(String label) Assume the variable folders is an array list of EmailFolder objects. Write code to add a new EmailFolder to the list.
