# OOP Standard deviation and mean array

the code needs to be structured like this.

see attached file for the assignment details

```package arrays;

import java.util.Arrays;
import java.util.Scanner;

public class TestArrays1 {

//fields
Scanner input = new Scanner(System.in);
private double[] anotherList = new double;//array of size 10
private double mean;
//private double standardDeviation;

public double[] getAnotherList() {

return this.anotherList;

}

public void setAnotherList(double value, int i) {

this.anotherList[i]= value;

}

public double getMean() {
return mean;

}

public void setMean(double mean) {
this.mean = mean;

}

public void playWithArrays() {

System.out.print("Enter ten numbers ");//prompt user

//fill array here
for (int i = 0; i < anotherList.length; i++) {
anotherList[i] = input.nextDouble();//fill the array
//System.out.print(anotherList[i] + " ");
}//end for loop

//loop through and print array
//for (int i = 0; i < anotherList.length; i++) {
//	System.out.print(anotherList[i] + " ");
//	}//end for loop

}//end method playWithArrays

public void calculateMean() {
for(Double num: getAnotherList()) {//short version of for loop
setMean(getMean() + num);

}

setMean(getMean() / getAnotherList().length);//set mean again
}

@Override
public String toString() {
return "The list of numbers is " + Arrays.toString(anotherList) + "the mean is: "
+ getMean() + "]";

// Arrays.toString(getAnotherList())

}

public void loop() {

this.playWithArrays();
this.calculateMean();

System.out.printf("The Mean is: %.2f", this.getMean());
}

public static void main(String args[]) {

TestArrays1 anArrayObj = new TestArrays1();

anArrayObj.loop();

//System.out.print(anArrayObj);

}

}

```
