need help with arrays

[njabulo ngcobo]

hello guys please help

/*1.1 Write a class to do the following:
a. Declare an array called arr1 to contain 10 cells of type integer.
b. Write a method to input 10 numbers into the array
c. Write a method to find and return the sum of the numbers in the array
d. Write a method to receive the sum. Find and return the average.
e. Write a method to receive the sum and average, output these values.
f. Write the test driver class to call up the methods.
*/

import java .util.*;
public class Array1
{
	public static void main (String [] a)
	{
		int [] arr1 = new int [10];
	}
 
	public void inputNumber()
	{
		Scanner console=new Scanner (System.in);
		System.out.println("Enter as number");
		int arr1=console.nextInt();
	}

HOW DO I FIND THE SUM (NUMBER C )

[GregBrannon]

Iterate the array (inspect each element) and add each to an integer variable, something like:

int total;
for ( int i : arr1 )
{
    total += i;
}

Note: you have declared the array in the main method, therefore the inputNumber method does not have access to it. You need to pass it as a parameter or make it an instance variable and use OO principles.
