JAVA: There are three errors with the program below (issues which would prevent the program from compiling). State what the errors are and why they occur. import java.util.Scanner; import java.io.FileOutputStream; import java.io.FileInputStream; import java.io.IOException; public class MyClass extends AnotherClass, ThirdClass { private int i; private String s; public MyClass(String s) { this.s = s; i = s.length(); } public abstract int doSomething(); public void readString() throws IOException { FileInputStream inFile = new FileInputStream("Text.txt"); Scanner scan = new Scanner(inFile); s = scan.next(); i = s.length(); inFile.close(); scan.close(); } public void writeString() throws IOException { FileOutputStream outFile = new FileOutputStream("Text.txt"); PrintWriter pw = new PrintWriter(outFile); pw.println(s); outFile.close(); }  }

USING JAVA: Part A) Implement a superclass Appointment and subclasses Onetime, Daily, and Monthly. An Appointment has a description (for example, “See the dentist”) and a date. Write a method,                                           occuresOn(int year, int month, int day) The check whether the appointment occurs on that date. For example, for appointment, you must check whether the day of the month matches. This fill an array of Appointment objects with a mixture of appointments. Have the user enter a date and print out all appointments that occur on that date. Part B) Improve the appointment book by giving the user the option to add new appointments. The user must specify the type of the appointment, the description, and the date.

For beginning Java, two things 1) I got this error from my code and how and where can I fix it:  Main.java:133: error: reached end of file while parsing } ^ 1 error 2) I was told my code is too long and needs to be separate files. How can I fix this into separate Java files? 3) I need to Draw the UML diagram using MS Word or PowerPoint for the classes and implement them.  My original assignment is attached. Here's my code: import java.io.BufferedReader;import java.io.FileReader;import java.io.IOException;import java.time.LocalDate; class Person {    private String name;    private String address;    private String phoneNumber;    private String emailAddress;     public Person(String name, String address, String phoneNumber, String emailAddress) {        this.name = name;        this.address = address;        this.phoneNumber = phoneNumber;        this.emailAddress = emailAddress;    }     @Override    public String toString() {        return "Person: " + name + "\nAddress: " + address…

In Java, a class can only inherit from one other ------- . A class can, however, extend many ----------.

Java. Code: public class Person{// PLEASE START YOUR CODE HERE// *********************************************************// *********************************************************// PLEASE END YOUR CODE HERE//constructorpublic Person(String firstName, String lastName){this.firstName = firstName;this.lastName = lastName;}public String toString(){return firstName + " " + lastName;}}

Use the Java program in below, implement encapsulation on the property name, and use getters and setters to unhide the name: class Animal1{String name;  public void eat(){System.out.println("I can eat");}} class Dog extends Animal1{public void display(){System.out.println("My name is " + name);}} public class Lab06_A{public static void main(String[] args){  Dog labrador = new Dog();    labrador.name = "Rohu";labrador.display();  labrador.eat();} }
