Brianna is taking a backpacking trip in the wilderness and wants to back up the photos from her camera. Which type of storage de
Katen [24]

Answer:

<u><em>C</em></u>

Explanation:

Flash drives usually have an input (E.G. one of those android charger connectors), so just plug that into your camera, and load the flash drive with the photos. Then go home and plug the USB on the flash drive into your PC. If there isn't already, a folder will be made in your "Pictures" folder on your PC, to which you can open the folder, and then your photos should be there. From there you can open them, print them, etc.

Hope this helped, and sorry if I didn't answer in time.

Write a program to create an interface Shape containing the method declarations of area and perimeter. Then, create a class Rect
irakobra [83]

Answer:

Explanation:

An interface is similar to a class, to create an interface we use interface keyword, in an interface there can be abstract methods and constants only,we can not instantiate an interface.All the variables declared inside an interface are public,static and final  by default.

While using interface child class must use implements keyword

We can define an  interface by using below syntax-

<interface> <interface-name>{

}

For example lets create Shpae interface

interface Shape{

public int area(int length, int width);

public int perimeter(int length, int width);

}

Now lets create Rectangle class-

class Rectangle implements Shape{

public int area(int length, int width){

int area = 0;

area = length * width;

return area;

}

public int perimeter(int length, int width);

int perimeter = 0;

perimeter = 2*(length+width);

return perimeter ;

}
