tree data structure in java

package MyPackage;

    static class Node {    
    int value; 
        Node left, right; 
          
        Node(int value){ 
            this.value = value; 
            left = null; 
            right = null; 
        } 
    } 
       
    public void insert(Node node, int value) {
        if (value < node.value) { 
          	if (node.left != null) {
