2. Consider the following class definitions:public class BClassprivate int x;public void set(int a){x = a;}public void print()System.out.print(x);}public class DClass extends BClass{private int y;public void set(int a, int b)//Postcondition: x =a; y=b;}public void print( ) {..}a. Write the definition of the print method of DClass that overrides it.b. Write the definition of the method set of the class DClass.||

In print method, we have to print both x and y values and to print value of x we can simply invoke…

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…
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.
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.
