Shuffling elements within rows of a 2D array (JAVA)

How would I shuffle the elements within the rows of a 2D array such that if I had:

{{'a', 'b', 'c', 'd'}, {'e', 'f', 'g'}, {'h', 'i','j','k'}

it would turn to something like:

{{'d', 'b', 'a', 'c'}, {'g', 'f', 'e'}, {'i', 'j','k','h'}

Basically, how do I get each 1D array in a 2D array to shuffle its elements?

Please help - I'm not sure how to start!
