public class Father { public String name; public int age; // customer name Father(){ name=”Hassan”; age=50;} public void display(){ System.out.println(“Name:”+name); System.out.println(“Age:”+age); } } 1. Based on Figure 3, create a class named Child that inherits the Father class. Declare an instance name location (String) for class Child. 2. Define a constructor in class Child and give an appropriate initial values for the instance (name, age, location). 3. Define a method display () in class Child, execute the display ( ) method in superclass using the keyword super. Method display ( ) in class Child should print the information of name, age and location 4. Create other class named Main for the main method and create 2 objects for the 2 classes (Father and Child). Then execute the display ( ) method for Father and Child. Example of the output as in Figure 4: Father's info: Name: Josh Age: 50 Child's info: Name: Christy Age: 20 Location:…

Which member functions of the class base are protected? b. Which member functions of the class base are inline? c. Write the statements that derive the class myclass from class base as a public inheritance. d. Determine which members of class base are private, protected, and public in class myclass.

public class date { private int day; // from 1 to 31 private int month; // from 1 to 12 private int year; // from 2000 upwards public void advance (); // move to next day }; Implement a constructor that initializes new objects of date class to be set to the 1st of January 2000. Implement setters for day, month, and year. Implement the advance method, which moves to the next day, ensuring that all data members are updated appropriately.
The Temperature class is an abstract class with two abstract methods. Create the Conversion class which inherits from Temperature. Use the formulas below to help with the temperature conversions. CODE: abstract class Temperature { public abstract double celsius(double temp); public abstract double fahrenheit(double temp);} //add class definitions below this line //add class definitions above this line public class Exercise3 { public static void main(String[] args) { //add code below this line Conversion c = new Conversion(); //add code above this line }}
Q 1: Access class members from the same package Note: ClassA and ClassB in this question are in the same package. public class ClassB { public int x = 1; int y = 2; private int z =3; } public class ClassA { public static void main(String[] args) { ClassB cb = new ClassB(); // System.out.print(cb.x); /* 1 */ // System.out.print(cb.y); /* 2 */ // System.out.print(cb.z); /* 3 */ } } 1.1- Which statement(s) are true? Choose all that apply. a. If statement 1 is uncommented, the code prints "1" to the output. b. If statement 2 is uncommented, the code prints "2" to the output. c. If statement 3 is uncommented, the code prints "3" to the output. .d. This code does not compile 1.2- Try to do the following: • Declare a character type variable myChar in the class ClassB, the variable myChar shouldn't be accessible through the object cb. Add a statement to the classA to test whether myChar is accessible.
JAVA Language Caesar Shift Question: Modify the Caesar class so that it will allow various sized shifts to be used, instead of just a shift of size 3. (Hint: Use an instance variable in the Caesar class to represent the shift, add a constructor to set it, and change the encode method to use it.) import java.util.*; public class TestCipher { public static void main(String[] args) { int shift = 7; Caesar caesar = new Caesar(); String text = "hello world"; String encryptTxt = caesar.encrypt(text); System.out.println(text + " encrypted with shift " + shift + " is " + encryptTxt); } } abstract class Cipher { public String encrypt(String s) { StringBuffer result = new StringBuffer(""); // Use a StringBuffer StringTokenizer words = new StringTokenizer(s); // Break s into its words while (words.hasMoreTokens()) { // For each word in s…

Based on Figure 3, create a class named Child that inherits the Father class. Declare an instance name location (String) for class Child. ii. Define a constructor in class Child and give an appropriate initial values for the instance (name, age, location).
