Urgent java programming question.Pls help

Q1. Generate 10 thousand random integers with values in the range between 1 to 100.

Q2. Store each randomly generated number into a node and then attach the node to a linked list. The list must be in descending order at all times ââ?¬â?? when nodes are attached and at the end of the last attach operation.

Q3. Measure the required time to sort those random numbers into ascending order.

Q1 answer:

import java.util.Random;

public class Question_1 {

public static void main(String[] args) {

Random rndNumbers = new Random();

int rndNumber = 0;

System.out.println("Random Number 1 - 100");

for (int nbr = 1; nbr < 11; nbr++) {

rndNumber = rndNumbers.nextInt(100) + 1;

System.out.println("Random Number: " + rndNumber); } } }
