This is what i have.
I need to add main with input and display. I need to use a linked list to show, a family tree. I wasn't given a clear explanation as to how the main method should look, so I'm very confused. I'm not sure how to go about writing the main.
public class FamilyTree
{
private class Node
{
String value;
Node left, right;
Node(String val)
{
value = val;
left = null;
right = null;
}
Node(String val, Node leftChild, Node rightChild)
{
value = val;
left = leftChild;
right = rightChild;
}
}
private Node root = null;
public boolean root(String x)
{
if (root == null){
root = new Node(x);
return true;}
else
return false;
}
public boolean addLeft(String p, String x)
{
Node parent = locate(p);
if (root == null ){
return false;}
else if (parent != null && parent.left == null){
parent.left = new Node(x);
return true;}
else
return false;
}
public boolean addRight(String p, String x)
{
Node parent = locate(p);
if (root == null ){
return false;}
else if (parent != null && parent.right == null){
//Adds node
parent.right = new Node(x);
return true;}
else
return false;
}
public Node locate(String p)
{
return locate(p, root);
}
}

I wasn't given a clear explanation as to how the main method should look If this is the case I would go to your teacher and ask for clarification. We know less about the requirements of your project than you do

writing a main method- what have you tried so far? Dumping some other non-relevant code doesn't help. TBH a simple search forjava main methodwill take you half way there.
