Hi,  
I am working on a class assignment but I am stuck.

The assignment is

1. Create an **int** array called **salesFigure** that will hold 5 elements.
2. Use a for loop to print all the elements. (They should all be 0 since no information has been assigned.)
3. Assign the 5 elements in the array by index location starting at index 0 and through index 4 in this order: (250, 1000, 2500, 4500, 3300)
4. Print the array using a for loop

Here is what I have.

```auto
int[] salesFigures = new int {250, 1000, 2500, 4500, 3300};
numbers[0] = 250;
numbers[1] = 1000;
numbers[2] = 2500;
numbers[3] = 4500;
numbers[4] = 3300;
  
for (int i = 0; i <salesFigures; i++)

{
System.out.println(salesFigures[i]);
}

```

I get an error of

> expecting DOT, found “salesFigures”

What am I missing?  
Thanks

Hi Awal, you have forgot the size method:

```auto
for (int i = 0; i <salesFigures.size(); i++)

```

Keep us up to date!

Thank you Dennis, I made the change but it still is throwing an error. Also where would I know the size based on the directions?

```auto
int[] salesFigures = new int{250, 1000, 2500, 4500, 3300}; // THIS IS WHERE THE YELLOW IS
numbers[0] = 250;
numbers[1] = 1000;
numbers[2] = 2500;
numbers[3] = 4500;
numbers[4] = 3300;
  
for (int i = 0; i <salesFigures.size(); i++)

{
System.out.println(salesFigures[i]);
}

```

Hops… I miss:

```auto
for (int i = 0; i &lt;salesFigures.length; i++)

```

Thanks Dennis, I am still getting errors. Sad part is this is only the first half of the assignment. This is going to take me forever.

There is a tutorial on arrays

See Website

Since (2) requieres 0 output for all members of the array, shorten your first line before the =

Then for loop with println

Then assign values (you have those 5 lines already)

Then again do the println

Dead easy
