A farmer with his wolf, goat and cabbage come to the edge of a river they wish to cross. There is a boat at the river�s edge. But, of course, only the farmer can row it. The boat also can carry only two things (including the rower) at a time. If the wolf is ever left alone with the goat, the wolf will eat the goat; similarly, if the goat is left alone with the cabbage, the goat will eat the cabbage. Devise a sequence of crossings of the river so that all four characters arrive safely on the other side of the river.
I need java code which finds a solution to this problem.
