Question

  Given the following class for the nodes in a linked list: public class Node {    ...    public Node getNext() {...}         // return next field    public int getData() {...}         // returns data }  Assuming that the variable head points to (i.e. contains the address of) the first node of a linked list,  write the statements to find the first occurrence of the data value x in the linked list. For example, find(4) would return something like "Found at node position 20" or "Not found" Assume that the nodes in the linked list are counted starting from 1. Your statements will be inserted inside a method like the following:    public String find(int x) {       // Whatever statements you provide in response to this question will        // be inserted here BY THE SYSTEM and then compiled and tested as part of       // a larger program which does many other things with the linked list    }

Explanation / Answer

public String find(int x) { int i = 1; Node temp = head; while (temp != null) { if(temp.getData() == x) { return "Found at node position " + i; } temp = temp.getNext(); i++; } return "Not found"; }
