I'm trying to write a method that can transfer an array into a Binary tree. I know the code is not right, I run it and hope it would show something that I can continue to fix it. But it just kept loading without any error or result. May anyone give me some advice, please!
Here is the BST class:

```
public class BSTNode {
    private String data;

    private BSTNode left;
    private BSTNode right;

    public BSTNode(String data) {
        this.data = data;
        this.right = null;
        this.left = null;
    }

    public String getData() {
        return data;
    }

    public void setData(String data) {
        this.data = data;
    }

    public BSTNode getLeft() {
        return left;
    }

    public void setLeft(BSTNode left) {
        this.left = left;
    }

    public BSTNode getRight() {
        return right;
    }

    public void setRight(BSTNode right) {
        this.right = right;
    }
}

```

And my method:

```
public BSTNode fromArray(String[] array, int start, int end) {
    int i = start;
    BSTNode root = new BSTNode(array[i]);
    BSTNode current = root;
    BSTNode parent = null;
    while (i <= end) {
        if (array[i].compareTo(current.getData()) < 0) {
            parent = current;
            current.setLeft(current); //Should I put current.setLeft(root) here?
        } else {
            parent = current;
            current.setRight(current);
        }
        // Create the new node and attach it to the parent node
        if (array[i].compareTo(parent.getData()) < 0) {
            parent.setLeft(new BSTNode(array[i]));
        } else {
            parent.setRight(new BSTNode(array[i]));
        }
        i++;
    }
    return current;
}

```

Thank you for your time!
