Java Program To Find Decimal Equivalent Of Binary Linked List

// Java Program to find decimal value 
// of binary linked list 
class GFG{
    
// Link list Node 
static class Node 
{ 
    boolean data; 
    Node next; 
}; 

// Returns decimal value of binary 
// linked list
static int decimalValue(Node head) 
{ 
    // Initialized result 
    int res = 0; 

    // Traverse linked list 
    while (head != null) 
    { 
        // Multiply result by 2 and 
        // add head's data 
        res = (res << 1) + (head.data?1:0); 

        // Move next 
        head = head.next; 
    } 
    return res; 
} 

// Utility function to create a 
// new node.

    Node temp = new Node(); 
    temp.data = (data == 1 ? 
                 true : false);

// Driver code
public static void main(String args[])
{ 
    // Start with the empty list 
    Node head = newNode(1); 
    head.next = newNode(0); 
    head.next.next = newNode(1); 
    head.next.next.next = newNode(1); 
    System.out.print("Decimal value is " + 
                      decimalValue(head));
