Hey bros. I made a program that prints out random numbers in a linked list. I want to have the index number next to each of the random numbers in the list. I guess for example like:
1 25
2 123
3 56
ect.
Here's m program so far, and it only sorts and prints out the list, but doesn't have an index next to each random integer. I think you use a list iterator to do this, but I can't figure it out... my output right now is like [23 58 129] but I kinda of want it to be like the list I made above.
Here's the code.
import java.util.*;
import java.io.IOException;
import java.util.Scanner;
import java.util.Random;
public class LinkedListProgram
{
public static void main(String[] args) throws IOException
{
int i,number, ran;
Scanner sc = new Scanner(System.in);
LinkedList<Integer> list = new LinkedList<Integer>();
ListIterator li;
String line;
Random random = new Random();
int pick = random.nextInt(150);
System.out.println("Enter # of nodes");
number = sc.nextInt();
if (number > 0)
{
for (i = 0; i < number; i++)
list.add(1+ (int)(Math.random()*150));
Collections.sort(list);
System.out.print(list + "\n");
}
else
System.out.println("\nnumber is less than 0\n");
}
}
Any helps is SUUUUPER APRECIATED. Thanks so much for all your times!
