Recursive Binary Search Tree not printing data in Java
===

I am currently learning java by writing my programs from C++ to Java.
I am trying to print the data using recursive binary search tree, but its not printing

Here is my code:



public class PersonRec {

	int bribe;
	PersonRec lchild;
	PersonRec rchild;	
}

import java.util.Scanner;

public class Tree {

	private PersonRec root;
	
	public Tree()
	{
		root = null;
	}
	
	
	public void Add()
	{
		
		int aBribe;
		Scanner scan = new Scanner(System.in);
	

		
		System.out.println("Enter person's contribution: ");
		aBribe = scan.nextInt();
		
		Insert(root, aBribe);
		
	
	}
	
	public void Insert(PersonRec root, int aBribe)
	{
		if(root == null)
		{
			root = new PersonRec();
			root.rchild = null;
			root.lchild = null;
			
			root.bribe = aBribe;
		}
		
		else if(aBribe < root.bribe)
		{
			Insert(root.lchild, aBribe);
			
		}
	
		else
		{
			Insert(root.rchild, aBribe);
		}
	}
	
	public void view()
	{
				
		if(root == null)
		{
			System.out.println("Tree is empty" + "\n");
		}
		
		
		else
			DisplayTree(root);
	}
	
	public void DisplayTree(PersonRec root)
	{
		
		
		if(root == null)
			return;
		
			DisplayTree(root.lchild);
			System.out.println(" " + root.bribe);
			System.out.println("\n");	
			DisplayTree(root.rchild);
	
	}
	
	
	
	
	public static void main(String args[])
	{
	
		Tree myList = new Tree();
		
		int choice;
		
		
		do
		{
			Scanner scan = new Scanner(System.in);
			
			System.out.println("\nMenu\n");
			System.out.println("==============================\n\n");
			System.out.println("1. Add student to waiting list\n");
			System.out.println("2. View waiting list\n");
			System.out.println("3. Exit program \n_");
			System.out.println("Please enter choice: ");
			choice = scan.nextInt();
			
		
			switch(choice)
			{
			case 1: myList.Add();
			break;
			
			case 2: myList.view();
			break;
			
			
			}
			
		}
		while(choice != 3);	
		
	}


	
}


When I type 1, i insert a bribe amount example: 23
when i type 2 again fro the menu its not being inserted in my tree it says, "tree is empty"

Thanks
