This is based on LinkedLists. Please complete the methods max()and threshold(). I'd greatly appreciate it. There is a typemismatch in my first method and I dont know how to get around it.I've commented on the line with the type mismatch. Please write acorrect method in the answer so I can compare it to my wrongmethod

public class Node {
   public T info;
public Node link;
public Node(T i, Node l) {
   info = i; link = l;
   }
}

class LinkedList> {
  
protected Node head = null;
public LinkedList add(T el) {
head = new Node(el, head);
return this;
}
public void print() {
for(Node node = head; node!=null; node=node.link) {
System.out.print(node.info+\" \");
}
System.out.println(\"\");
}
  
public T maxValue() { // Note: Recursive methods not allowed, usingnew key word not allowed, no iterators allowed
   if (head == null) {
   return null;
   }
   else {
   Node temp = head;
   if (temp.link == null) {
   return temp.info;
   }
   else {
   T max = temp.link; //type mismatch
   if (temp.info.compareTo(max) > 0)
   max = temp.info;
   return max;
   }
}
}
  
public void threshold(T thres) {//Note: Recursive methods notallowed, using new key word not allowed, no iterators allowed

}

public static void main(String args[]) {
  
LinkedList list = new LinkedList();
System.out.println(list.maxValue()); // should be null
list.add(20).add(30).add(10);
System.out.println(list.maxValue()); // should be 30
list.threshold(40);
list.print(); // should print out all elements
list.threshold(30);
list.print(); // should print out 10 20
list.threshold(10);
list.print(); // should print nothing
}
