Number. That method will be called compare and it will take a
Number as an argument and will return an integer.
Your compare method will behave as follows:
• Case 1: If this is numerically greater than other, then
return 1
• Case 2: If this is numerically lesser than other, then return

Task 1.2
In the ExampleArrays class, you will use the design recipe to
write a method called sumPairs that will take 2 Pair[] as
arguments and return a Pair[]. Each element of the returned
Pair[] will be the result of adding both Pair objects at the
same index in the 2 Pair[] given as arguments. If the 2 Pair[]
are of different lengths, then you will sum the pairs up to the final
pair of the shortest Pair[]. You may safely ignore the remaining
Pair objects of the longer Pair[]. If any Pair[] is empty,
you will return an empty (length of o) Pair [].
then
In the file ExampleArrays.java, you will add a new class
OUTSIDE the ExampleArrays class called Pair. It will have
two fields of type int called a and b. It's constructor will initialize
both fields to be the value as specified by the arguments given to
the constructor.
Adding 2 Pair objects means to sum their a fields together and
to sum their b fields together
Task 1.3
In the ExampleArrays class, you will use the design recipe to
write a method called onRegionEdge that will take a Region []
and Point as arguments and return a Region []. The resulting
Region [] will consist of all regions where the Point given as
argument lies on the edge of the region. If the Region[] given
as argument is empty, return an empty Region [].

Expert Solution

Step 1

public class Pair {
int a, b;

Pair(int a, int b) {
this.a = a;
this.b = b;
}
}

class ExampleArrays {

public Pair[] sumPairs(Pair[] p1, Pair[] p2) {
Pair[] result;
if (p1.length == 0 || p2.length == 0)
result = new Pair[0];
else if (p1.length <= p2.length) {
result = new Pair[p1.length];
for (int i = 0; i < p1.length; i++) {
result[i] = new Pair(p1[i].a + p2[i].a, p1[i].b + p2[i].b);
}
} else {
result = new Pair[p2.length];
for (int i = 0; i < p2.length; i++) {
result[i] = new Pair(p1[i].a + p2[i].a, p1[i].b + p2[i].b);
}
}
return result;
}
