IndexError: index 168 is out of bounds for axis 0 with size 168 code example

Example: index 1 out of bound for length 1 java

1 means index 1 is invalid and it's out of bound i.e. more than the length of the array.
  Since array has a zero-based index in java , this means you are trying to access the second element of
  array which only contains one element.
