    Default Insertion sort

    i have to write this program

    1) A “MyNum” class that will generate a random integer number from 1 to 200.
    2) A “Time” class that will return the system time with sufficient resolution to show the time between insertions. I suggest System.nanoTime().
    3) A “Node” class that will encapsulate the integer number and the Time it was generated.
    4) And a “Storage class” class that will contain the all the SORTED Nodes using an insertion sort.
    a. This class should have a “add” method to add in each node.
    b. And method(s) so the driver class may display the sorted list of nodes
    5) The “main” or driver class.

    So far i have written MyNum class and Time i am stuck on the Node class. When i run it, it only gives me the random number it does not give me the time it took for it to generate.

    Node Class
    HTML Code:
    class Node {
     
        private long time; 
        private int num;
             
              
        public Node (){
            num=MyNum.genRandom();
            time = Time.time();
             
        }
             
      
        public String toString (){
             
             
        return "Number" + num + "Time" + time;
     }
         
     
    }



    Time CLASS
    HTML Code:
    public class Time {
     
        public static long time(){
            return System.nanoTime();
        }
    }
    Random Number
    HTML Code:
    import java.util.Random;
     
     
    public class MyNum {
         
     
            static Random number = new Random();
     
     
            public static void main(String[] args) {
     
                for (int i =0; i < 1 ; i++)
                {
                    System.out.println( genRandom());
                }
     
            }
            public static int genRandom(){
                return number.nextInt(200);
            }
     
            }
