A window with the title “Welcome Home”

What is the output of the following code?

int x = 100;

int y = 200;

if (x > 100 && y <= 200)

System.out.println(x + “ “ + y + “ “ + (x + y));

else

System.out.println(x + “ “ + y + “ “ + (2 * x - y));

Declare the Person superclass as abstract. Add this abstract method to the class:

public abstract void eat(String food);

Both the Student and Employee class inherit from abstract superclass Person, and provides an implementation for eat() which displays that the student or employee is eating a certain food.

(Note what happens if you don’t implement eat().)

Create an interface called StudentInterface. This interface has the following abstract method:

public void study(String subject);

The Student class implements this interface, and provides an implementation for study() which displays that the student is studying a certain subject.

(Note what happens if you don’t implement study().)

Write a program in Python programming language, which allows the user to input an integer value. Based on the input values, the program should perform the following tasks:

⦁ If the entered value is negative then it should print “Factorial does not exist for negative numbers”.

⦁ If the entered value is 0 then it should print “The factorial of 0 is 1”.

⦁ Calculate and display the factorial of the given integer.

Write a program in Python programming language, which allows the user to input a number and upper limit, and based on the input values, the program should perform the following tasks:

⦁ Check whether the value entered by the user is a positive integer.

⦁ Generates an error massage in case of negative integer.

⦁ Generate a table of given number.

⦁ Upper limit for table will be get from user.
