I am building a 8 puzzle search and want to build a data base of the moves to avoid repeating the same move. I have stored the values of the table as an array and want to see these values in the hashmap. The problem is when I check the hashmap all the values are the same in the arraylist. You can compile the program and see it. Any ideas about th? mistake I am making>
