[Solved] How to avoid printing empty array elements? [closed]

To print empty elements:

for (int i = 0; i < arr.length; i++) {
    if (arr[i] == null || arr[i].trim().isEmpty()) {
       System.out.println("Element " + i " + " is null or empty.");
    }
}

The print non-empty elements:

for (int i = 0; i < arr.length; i++) {
    if ( arr[i] != null && !arr[i].trim().isEmpty())) {
       System.out.println(arr[i]);
    }
}
