Programming Java: Solution to three water jug problem infinite loop error -- 2

I am trying to write code that solves similar to this: [login to view URL]) , except the problem uses three water jugs. You start with one of the jugs being full and the others being empty, then choose two out of the three jugs and pour the contents of one of these into the other one until either one is empty or the second is full, and this can be repeated multiple times until the the desired amount of water in a jug is achieved. cap[] is an integer array of the capacities of the containers and d is the desired number to be obtained, both entered by input. If no solution can be obtained then no output should be produced. The following input: 20 5 3 4 should produce the following output: 20 0 0 15 5 0 15 2 3 18 2 0 18 0 2 13 5 2 13 4 3 Where 20 5 3 are capacities of the three containers and 4 is the desired number to be reached ie the variable d. The code requires using no more advanced data structures than arraylists, linkedlists, stacks, and queues. I have already have code for this program however it appears to get stuck in an infinite loop when given the following input to test it out: 81 52 43 21 My request is to have the code fixed so it can work with the prior input to not do infinite loop. The code is linked.
