I need to write a method to ensure that all of the nodes of a BST (Binary Search Tree) are valid. For a node to be valid, 2 things must hold:The left child must be less than the current node's valueThe right child must be greater than the current node's value.I decided to write a helper method that checks an individual node. Conceptually, it's easy enough, but the end result looks clumsy. I started out with://Returns true if the left node is less than the current node, and the right// node is greater than the current node.private boolean nodeIsValid() {    if (hasLeft() && left.compareTo(this) > 0) return false;    if (hasRight() && right.compareTo(this) < 0) return false;    return true;}Then I realized I could combine the 2 guards into a single check:private boolean nodeIsValid2() {    if (hasLeft() && left.compareTo(this) > 0 ||        hasRight() && right.compareTo(this) < 0)            return false;    return true;}But it seems pretty bulky still. Plus, given I'm just returning true or false based on a condition, I imagine this could be compacted down into a single statement (although I don't know if that would help readability).Which of my two versions is more pleasant and readable?Can the check be cleanly reduced to a single statement?
Tiny function to ensure a node of a BST has a valid relationship with its children

Which of my two versions is more pleasant and readable?The second is just bad as said in the comment by JK01.It should be justreturn !(hasLeft() && left.compareTo(this) > 0 ||    hasRight() && right.compareTo(this) < 0);and then you could use De-Morgan rule to get rid of the outer negation. However, something likereturn (!hasLeft() || left.compareTo(this) <= 0) &&    (!hasRight() || right.compareTo(this) >= 0);has nothing to do with the idea it represents. Sticking with the original and adding braces is best:private boolean nodeIsValid() {    if (hasLeft() && left.compareTo(this) > 0) {        return false;    }    if (hasRight() && right.compareTo(this) < 0) {        return false;    }    return true;}It's easily extensible: Just add another condition.It's structured: 2 simple expressions instead of a multiline monster.It corresponds exactly with what could go wrong.
