Create the Grid Walker program in Java based in the following instructions.

To start your program, ask the user for a number of rows and columns. Then create a grid of the specified size. One space in the grid (at random) should have the letter T; each other space should have either U, D, L, or R at random. Display the contents of the grid.

Following that, ask the user for a starting row and column. Starting at that position, follow the directions indicated by the letter (up, down, left, or right) until one of three conditions occurs:

1) you go off the grid,

2) your path intersects itself, or

3) you reach the spot marked T.

Once one of those conditions occurs, specify which condition and print the grid with your path marked in stars. If you reached T, do not replace T with a * but do specify how many steps it took to reach T.
