Hmm you just sum all of the elements in your "myArr". for x=0: 0+6=6 for x=1: 6+42= 48 for x=2: 48+3=51 for x=3: 51+7=58 The length of your array is 4 so you are counting from 0 to 3. Finish

you loop over your array. loop# |x |myArr[x] |sum 1. |0 | 6 |6 2. |1 |42 |6 + 42 = 48 3. |2 | 3 |48+ 3 = 51 4. |3 | 7 |51 + 7 = 58

Gabriellah Palawo arrays have the length property which provides the length or capacity of the array. It gives the total space allocated during the initialisation of the array. Here's an example: // creating a new array of 5 elements int arr[] = new int[5]; // store some elements to the array arr[0] = 2; arr[1] = 4; // print length of array System.out.println(arr.length); //5 Calling the length element of the array arr[] will return 5.
