Visualizer for binary tree data structure in Java.

TreeVisualizer

A simple program to print all the nodes in the tree with a beautiful output. Connected by lines with clear paths, it's nice to look and easy to debug a tree.

Getting Started

Download TreeVisualizer.java and put it in the same directory so you won't need to import anything

Usage

1. Put TreeVisualizer.java in the same directory with the Node file (to implement) and Tree file (to print)
2. Implements Visualized from TreeVisualizer to your Node class
3. Override getLeft, getRight, and getValue method with your values

class Node implements TreeVisualizer.Visualized {
  Node left, right;
  String name;
  
  ...
  
  @Override
  public TreeVisualizer.Visualized getLeft() {
      return this.left;
  }

  @Override
  public TreeVisualizer.Visualized getRight() {
      return this.right;
  }

  @Override
  public String getValue() {
      return this.name;
  }
}

4. If your Value is other than a String, you need to modify it to return your data type
5. Use the provided print method and put the tree's root as the argument

public class MyFile {
  public static void main(String[] args) {
    Tree tree = new Tree();
    TreeVisualizer.print(tree.root);
  }
}

or

public class MyFile {
  public static void main(String[] args) {
    Tree tree = new Tree();
    tree.print()
  }
}

class Tree {
  Node root;
  
  ...
  
  public void print() {
    TreeVisualizer.print(this.root);
  }
}
