Main function in the class BinarySearchTree is a simple test program that does the following...

In the first for loop,  it inserts the numbers, multiples of 37, starting from 37, till the number is divisible by 4000.
In Second for loop, Then it removes odd numbers less than 4000 from the tree.
and blah.. blah..

For you if you want to insert the data and remove them..use the insert and remove api's inside the BinarySearchTree class.

Here is the complete code and explanation of BinarySearchTree example...

Dont forget, the data you want to insert must have implemented Comparable interface.

Some Sample Code to insert the string object and remove the same string object

public class Test
{
     //To insert a new String into it..
     BinarySearchTree t = new BinarySearchTree( );
     t.insert("SomeString");

     //To remove the same String ..
     t.remove("SomeString");
}
