 1. In the `main` method we are taking a sample array `arr` and passing it to the `isArraySorted()` method to check if the array is sorted or not. This method returns a `boolean` value. `true` - if an array is sorted, `false` - if an array is not sorted
 2. In the `isArraySorted()` method, we are iterating over an array from index `0` to `n-1`, (`n`-length of the array) and we will check if the current number (number at index `i`) is greater than the next number ( number at index `i+1`).
 3. If the current number (number at index `i`) is greater than the next number ( number at index `i+1`), that means the array is not sorted, and we will return `false`.
-4. If the control came out of for loop, that means the array is sorted and we will return `true`.

 5. When we receive the `boolean` result `isSorted` we will print the output.

-## For array of custom object

-1. if custom object implements comparable (Coming Soon)
-2. if custom object does not implement comparable (Coming Soon)

 ## Conclusion
 
  we can check if the primitive arrays are sorted or not by comparing the adjacent array elements.
