It would be better if you post the code that you completed in your attempt to fulfill your project.

We do not provide code just for the asking, we help you understand what is wrong with your code.

all i need is how to do the find methode, since every node in the tree can have many children ( so i used an array for it) but now i can't figure a way to search the whole tree for a specific node.

- consider using java.util.List instead of array.
- about the search method:
Make it recursive, something like ( this will probably NOT work as is )
CODE

public Node find(Node nodeToFind){
  Node tmp;
  if( this.equals(nodeToFind) )
     return this; // found - this one
  for( Node child : childrenNodes ){
    tmp = child.find(nodeToFind);
    if( tmp != null ) // found in some of the children nodes
       return tmp;
  }
  return null; //not found
}
