In Java an abstract class cannot be sub-classed ?? True ?? False

mojhsa [17]

Answer:

False

Explanation:

An abstract class is a class declared abstract — it may or may not include abstract techniques. It is not possible to instantiate abstract classes, but they can be sub-classed.

Abstract method declaration

abstract void moveTo(double X, double Y);

Usually the subclass offers solutions for all of the abstract techniques in its parent class when an abstract class is sub-classed. If not, however, the subclass must be declared abstract as well.

Example

public abstract class GraphicObject {

// declaring fields

// declaring non-abstract methods

abstract void draw();

}

To pinpoint an earthquake's location, scientists need information from how many seismometers?

Mazyrski [523]

C. 3
Due to the different speeds of P and S waves, a single seismometers can determine the distance to an earthquake. So, for a single station, the localization is any point on a circle around the station. With 2 stations, you'll have two circles that intersect at two points. The 3rd station is needed in order to determine which of the 2 points is the actual earthquake.

#Write a function called random_marks. random_marks should #take three parameters, all integers. It should return a #string. # #

Bezzdna [24]

Answer:

def random_marks(apostrophe, quotation, apostrophe_quotation):

return "'"*apostrophe + "\""*quotation + "'\""*apostrophe_quotation

print(random_marks(3, 2, 3))

Explanation:

Create a function called random_marks that takes apostrophe, quotation, and apostrophe_quotation as parameters. Inside the function, return apostrophe sign times apostrophe plus quotation mark times quotation plus apostrophe sign quotation mark times apostrophe_quotation.

Note that plus sign (+) is used to concatenate strings. Also, if you multiply a string with a number, you get that number of strings ("#"*3 gives ###).

Then, call the function with given parameters and print
