How can I visualize tree traversal in Java?

You can use various visualization techniques like depth-first and breadth-first traversal. Would you like to see a code example?

Yes, please provide a code example for depth-first traversal.

Here's a simple example:

class Node {
    int value;
    Node left, right;
    Node(int item) {
        value = item;
        left = right = null;
    }
}

void depthFirstTraversal(Node node) {
    if (node == null) return;
    System.out.print(node.value + " ");
    depthFirstTraversal(node.left);
    depthFirstTraversal(node.right);
}

This will print the values in depth-first order.

How can I visualize the output of this traversal?

You can use libraries like JavaFX or Swing to create a graphical representation of the tree and its traversal. Would you like more details on that?
