Write a method in Java public static void swapWithNext( Node beforep ) to implement a swap between two adjacent elements by adjusting only the links (and not the data) using a single linked list. beforep is an input parameter that represents the node before the two adjacent nodes that are to be swapped.

I have already solved the problem but i do not understand how to implement a simple test class to test my program. Below is my code:

public class Problem1Swapping {

//Provided Node class to use for problem 1
private class Node {

public Object data;
public Node next;

public Node(Object data, Node next) {
this.data = data;
this.next = next;
}
}

public static void swapWithNext(Node beforeP){
Node p; //First Node to be swapped
Node afterP;//Second Node to be swapped

p = beforeP.next;
afterP = p.next;

p.next = afterP.next;
beforeP.next = afterP;
afterP.next = p;
}

}

public class Problem1SwappingTester {

public static void main(String args[]){
?????
}
}
