is_Balanced(Binary Tree)

#1

https://ide.geeksforgeeks.org/CMcmMiLv9K--- the code is running perfectly fine in geeks for geeks ide and showing correct result but in cb ide it is showing the following error upon submission-----

Main.java:2: error: class Main3 is public, should be declared in a file named Main3.java
public class Main3 {
^
1 error----------

please resolve the technical glitch as i think the code is pefectly fine

Hey @AbhishekAhlawat1102
Code is fine
Class Name must be Main:
updated code :

import java.util.*;
public class Main {

static Scanner scn = new Scanner(System.in);

public static void main(String[] args) {
	Main m = new Main();
	BinaryTree bt = m.new BinaryTree();
	System.out.println(bt.isBalanced());
}

private class BinaryTree {
	private class Node {
		int data;
		Node left;
		Node right;
	}

	private Node root;
	private int size;

	public BinaryTree() {
		this.root = this.takeInput(null, false);
	}

	public Node takeInput(Node parent, boolean ilc) {

		int cdata = scn.nextInt();
		Node child = new Node();
		child.data = cdata;
		this.size++;

		// left
		boolean hlc = scn.nextBoolean();

		if (hlc) {
			child.left = this.takeInput(child, true);
		}

		// right
		boolean hrc = scn.nextBoolean();

		if (hrc) {
			child.right = this.takeInput(child, false);
		}

		// return
		return child;
	}

	public boolean isBalanced() {
		return this.isBalanced(this.root).isBalanced;
	}

	private BalancedPair isBalanced(Node node) {
		if(node == null){
           BalancedPair bp = new BalancedPair(-1, true);
           return bp;
        }
        BalancedPair lb = this.isBalanced(node.left);
        BalancedPair rb = this.isBalanced(node.right);
        
        BalancedPair bm = new BalancedPair();

        bm.height = Math.max(lb.height, rb.height) + 1;
        int diff = Math.abs(lb.height - rb.height);
        bm.isBalanced = (diff <= 1 && lb.isBalanced && rb.isBalanced);
        return bm;
	}

	private class BalancedPair {
		int height;
		boolean isBalanced;
        BalancedPair(){

        }
        BalancedPair(int h, boolean flag){
            this.height = h;
            this.isBalanced = flag;
        }
	}

}
