Create a public class Dog that stores a single double age set by the constructor. (Reject negative ages using assert.) Dog should also provide a single class method named isOlder. isOrder should accept two Dog instances and return true if the first is older than the second, and false otherwise. You should also assert that both passed instances are not null.

Explanation:

The following is written in Java and has the methods as requested in the question...

class Dog {

   private double age;

   public Dog(double v) {

       assert v >= 0:" Not valid";

       this.age = v;

   }

   public boolean isOlder(Dog dog1, Dog dog2) {

       if (dog1.age > dog2.age) {

           return true;

       } else {

           return false;

       }

   }

}

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.

explanation:

assuming you are in the home page.

1) go to the upper right hand corner

2) click on your "profile picture"

3) go down to "edit profile"

4) it should be titled as "edit your profile", click on "profile picture"

5) choose a file

6) press "change"

you're profile picture is updated
