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().)
Light is incident on a diffraction grating that has 300 lines /mm. A diffraction pattern is observed. The angle between the central maximum and second order maximum was measured to be 250 . Calculate the wavelength of the light.
a silica optical fiber with a core diameter large enough to be considered by ray theory analysis has a core refractive index of 1.50 and a cladding refractive index of 1.47.determine the critical angle at the core-cladding interface.
