to create a program to calculate the sum of a set of numbers. to get the first number, the last number, count how many numbers there were in the set.
ScreenShot:

Code:

public class NumberStats {
private int number;
private int firstnumber;
private int lastnumber;
private int count;
private double average;
private int maximum;
private int minimum;
private int totalnumber;
private int numbermmount;

public int getnumber() {
return number;
}
public int getfirstnumber() {
return firstnumber;
}

public int getlastnumber() {
return lastnumber;
}
public int getcount() {
return count++;
}
public double getaverage() {
return average;
}
public int getmaximum() {
return maximum;
}
public int getminimum() {
return minimum;
}
public int gettotalnumber() {
return totalnumber;
}
public int getnumberamount() {
return numbermmount;
}
}
