Java error: method searchelement in class constructavltree cannot be applied to given types;

<pre>class ConstructAVLTree{
	private Node rootNode;
	public ConstructAVLTree(){
		rootNode = null;
	}
private boolean searchElement(int element){
	return searchElement(rootNode, element);
}

private boolean searchElement(Node head, int element){
	boolean check = false;
	while((head != null) && !check){
		int headElement = head.element;
		if (element < headElement){
			head = head.leftChild;

			head = head.rightChild;
		}
		else{
			check = true;
			break;
		}
		check = searchElement(head, element);
	}
	return check;
}
}

public class AVLTreeExample {
    
    public static void main(String[] args) {
    	Scanner sc= new Scanner(System.in);
    	ConstructAVLTree obj = new ConstructAVLTree();
    	char choice;
int ch = sc.nextInt();
    	switch(ch){
case 1:
    			System.out.println("Enter integer element to search: ");
    			System.out.println(obj.searchElement(sc.nextInt()));
    			break;
}
}
}

I am making a program that can add, remove elements (stacks and queues-like) and display elements in pre, in and post-order traversal. I tried changing boolean to void and default but didn't work and had more errors than expected. Hopefully someone can help me with this error, thank you.
