Program Sederhana Membuat Aplikasi Perkalian Bilangan Array menggunakan Bahasa Java

Source Code :

package tugasstrukturdata;

public class PerkalianArray {
    static class node

{

    int data;

    node next;

};



static node newNode(int data)

{

    node new_node = new node();

    new_node.data = data;

    new_node.next = null;

    return new_node;

}



static node push( node head_ref, int new_data)

{

    node new_node = newNode(new_data);



    new_node.next = (head_ref);



    (head_ref) = new_node;

    return head_ref;

}



static long multiplyTwoLists ( node first, node second)

{

    int num1 = 0, num2 = 0;

 

    while (first != null || second != null)

    {

        if (first != null)

        {

            num1 = num1*10 + first.data;

            first = first.next;

        }

        if (second != null)

        {

            num2 = num2*10 + second.data;

        }

    }

}

{

    while(node != null)

        System.out.printf("%d", node.data);

        if(node.next != null)

            System.out.printf("->");
