Create a class namely Circle and do the following: (i) Circle will have the following member variables: Point - an inner class having two members variables x and y representing the center and radius (a floating-point number) (ii) Crcate a method in the inner class namely getPoint() to print the point (x, y) that represents the circle center. (iii) Write a main method to create 10 random circles with the grid of (10, 10) and (70, 70).

Create a class Rectangle with parameters length, breadth, and color. Use appropriate data types andaccess specifiers. Write overloaded constructors to create objects of rectangle. First constructor takesall the three parameters. Second constructer takes two parameters length and breadth. If only oneparameter is given then user creates square of red color. Write methods to set and get the values oflength, breadth and color. Write methods to find length of the diagonal of rectangle and to display thecomplete details of rectangle with area. Create another class TestRectangle which uses allconstructors to create the different objects, uses appropriate set and get methods wherever required.Display the details of every rectangle.

Create a Main class. Create a static method in the main class isPalindrome and implement the functionality to check whether a number is a palindrome or not. Declare variables: inputNumber, reversedNumber, remainderNumber. Initialize the inputNumber and store it in the new variable originalNumber. Use a while loop and perform logic to print the reverse number of inputNumber. Compare reversed reversedNumber with originalNumber. After comparing the numbers, print "Palindrome” or "Not a Palindrome" to reflect the results. PalindromeNumberTest.java: public class Main { public static void main(String[] args) { // Paste the code for your tests here. } } PalindromeNumber.java: public class Main { public static void main(String[] args) { // Paste your code for testing a palindrome here. } }
3. Write a class Student having attributes to store the following data: Name, fathers’ Name, department, degree, enrolment, seat number, marks of three subjects. Also write a class to test all methods of Student class. Add the following methods in the above class. • int getTotal() : This methods returns the total of marks • void printTotal() Prints the total marks of Student • float getPercentage() this method calculates the percentage of a student • void printPercentatge() this method prints the percentage of student • char getGrade() this method calculates and returns the grade. • void printGrade() this method prints the grade of a student. • void printInfo() This method prints all information of the student.
JAVA PROGRAMMING - Create a class named "Shape" that has rhe abstract methods getArea() and getPerimeter(). - Create a class named "Rectangle", "Square", and "Circle". Override the methods getArea() and getPerimeter() with the right equation in getting the area and perimeter. - For rectangle, create attribute length and width. For square, side. For circle, radius Inputs: 1. Char input for Shape Type (Rectangle, Square, Circle). 2. Dimensions for specific type of Shape Output: Shape: Rectangle Length: 10 Width: 50 Area: 500.00 Perimeter 120.00
Create a class called Employee as a a derived class of the class Person. An employee record has an employee's name, address, gender(inherited from the class Person), an ID number whose type is String, an annual salary represented as a single value of type double, and a year the employee started work as a single value of type int. Your class should have a reasonable number of constructors and setter methods, as well as getter methods. Write another class containing a main method to fully test your class definition.
Define a class called Country. A Country has populationSize, area, capital, currency, and abbreviation (2-3 letters taken from the country name). Define at least two constructors, at least two getter methods, at least two setter methods, and Override the toString() and the equals() methods. The equals() method must return true if the two countries have the same name and same populationSize and false otherwise. The abbreviation is the first letter and the second letter of the country name and must be generated automatically (e.g. if the country name is Palestine the abbreviation is PA, if the country name is Jordan the abbreviation is JO.) Write a main method, define an array of country objects, read countries data from the user, if two countries have the same abbreviation add the last letter from the country name to the abbreviation of the country inserted last. Display countries whose area is greater than 10000 km2.

1. Create a class Employee with parameters name, id, designation, and basicSalary. Use appropriate datatypes and access specifiers. Use default constructor to create objects of employee. Write methods toset and get the values of parameters of employee. Write methods to find total salary of employee andto display the complete details of employee along with total salary. Create another class TestEmployeewhich creates array of n number of employees, uses appropriate set methods to set the values ofparameters of every employee. Display the details of each employee. (Total salary = basic salary + 80%of basic salary)
