Java queues and stacks are data structures used to store and manipulate a collection of elements. A queue is a first-in, first-out (FIFO) data structure, meaning that the first element added to the queue will be the first one to be removed. On the other hand, a stack is a last-in, first-out (LIFO) data structure, where the last element added to the stack will be the first one to be removed. In Java, queues and stacks can be implemented using the Queue and Stack interfaces, respectively, and there are several classes that provide implementations of these interfaces, such as LinkedList and ArrayDeque for queues, and ArrayDeque for stacks. **
