return true;
}else{
return false;
}
}

Ans: private static void printLevelOrderBST(Node node) {
if(queue.isEmpty()){
queue.add(node);
}
while(!queue.isEmpty()) {

System.out.println(" Value : "+myNode.val);
if(myNode.left != null ){
queue.add(myNode.left);
}
if(myNode.right != null){
queue.add(node.right);
}
}
