Understanding value trees

Understanding the value trees requires the understanding of how a tree structure is set up in Java. It is best described as a structure that does not use a linear representation of the data objects. The objects follow a hierarchical system where they are connected to each other in both a parallel and perpendicular manner.

The data present in a tree, such as the one created with a JSON structure, does not have the linear organization found in a simple array. The data elements that are present in a tree structure are usually saved in the form of nodes. There is a node at the tip of the structure, which is termed as the root node of the tree.

This tree structure is perfect when a linear presentation is simply not possible. This happens when there is a need to create a family of specific data elements. Java is able to deal with these trees since there are...
