Monte Carlo election battle simulation

Im very new to programming, I was thought java in an intense three week college prep course and am now studying software development.

In my data structures and algorithms lecture we were asked to write a program based on Monte Carlo Simulations and the Irish Election on Friday,

We have to calculate the probability that 3 specific candidates of the 6 will finish last in any order. The probabilities are gotten from converting odds that paddy power bookies have given.

I just have no idea where to start and how to go about it, all I have so far is

    import java.util.Random;
    import java.util.Scanner;

    public class election
    { 
     public static void main (String []args)
    {
      Scanner myscan = new Scanner(System.in);
      Random elect = new Random();
      Double probability;

      for(int i=1; i<10;i++)
      {
        probability=Math.Random();

        if(probability == 0.98)
         {
           System.out.println("Michael D.Higgins is 1st");
         }
        else if(probability == 0.038)
         {
          System.out.println("Sean Gallagher is 2nd");
         }
       else if(probability == 0.029)
         {
           System.out.println(" Peter Casey is 3rd");
         }
       else if(probability == 0.024)
         {
           System.out.println("Liadh Ni Riadh is 4th");
         }
      else if(probability == 0.007)
         {
           System.out.println("John Freeman is 5th");
         }
      else if(probability == 0.005)
        {
         System.out.println("Gavin Duffy is 5th");
        }
       }
      }
     }        

I realise this won't do as I want but I don't know where else to go, Sorry if this seems like a silly question but any and all help is greatly appreciated!!!! }

Sample from specific rows in a dataframe column [duplicate]

This question already has an answer here:

• from data table, randomly select one row per group 3 answers

The data: Using R studio, I have created a dataframe of Cluster data consisting of two columns: 1) Sequence Numbers and 2) Cluster they belong to.

Image reference: https://i.stack.imgur.com/3tXTt.png. Apologies for not being able to post the source code as it's part of a much larger ongoing project and can't be isolated.

The dataframe is 195 entries long. Column 1 is sequential from 1-195 while Column 2 consists of 10 cluster numbers that are repeated, according to which sequences belong to it. So for instance in the 20-row-excerpt of the dataframe I've printed out below you can see sequences 2-12 all belong to cluster 5.

 Seq Cluster
    1 10
    2 5
    3 5
    4 5
    5 5
    6 5
    7 5
    8 5
    9 5
    10 5
    11 5
    12 5
    13 4
    14 4
    15 3
    16 4
    17 4
    18 4
    19 2
    20 8

My aim: I would like to randomly sample one sequence from each of the 10 clusters and subset it into a new database.

So for instance: one random sampled sequence from sequences 2-12

However I am unsure how randomly sample only between each cluster separately.

By running:

nrow(unique(dfCluster))

I can receive an output of each cluster and one non-redundant sequence that belongs to it, but that's not exactly random it's just the first corresponding value per cluster group.

Author note: Please let me know if I can further clarify any of these steps, and apologies for it being rather long-winded

How can I create a loop to randomly assign values to each characteristic of an array of class instances

So I am creating a card game that requires different cards, so I created a card class in which I declared the string value names and other interger values that are the powers eg.Intelligence So I created an array of instances of these classes Their names are read from a text file and assigned to the name value The part I am having trouble with is the part where I need to create a loop to randomly assign values to each power of each instance of a class. Here's what I've done so far

But when I print out the values all the instances have the same value for their powers. Eg Card 12 Intelligence = 6 And Card 14 Intelligence = 6 Can anyone please help me with this issue, and any guidance will be highly appreciated Thank you

Instantiate Random Level after a certrain distance the player move

First of all, thank you for trying to help me! Like in subway runner, etc. the order of the gameobjects are really random, and every certain distance there's a new random GameObject (PowerUp). let me clarify, my question is that I create endless runner right now, for exp. there's a blade "level" (with many rotating blades), a lazer "level", monster "level", etc. I call them "levels" but I want that after a certain amount of distance the player moves, (for exp. 500 meters) a new RANDOM "level" will instantiate. for exp. someone start the game and the first level he does is the blade level, but if someone else also starts the game, there's a chance it would be the monster level, and after a certain amount of meters he passes, the last level is "destroyed" and the new RANDOM level (except the level he just did) is instantiated. I hope you catched what I'm trying to say, and could help me :) I'd appreciate really much any help at all! Thanks a lot!

Java drawing random numbers without repeating them [duplicate]

This question already has an answer here:

• Generating Unique Random Numbers in Java 16 answers
• Java generating non-repeating random numbers 8 answers

I am trying to write a bingo game on java and part of it is to draw random numbers from 1 to 20 but one number shouldn't be drawn more than once. So my question is how can I do that?

Complicated Lotto Numbers Generator - Python

I'm old and am learning python to keep the old noodle sharp and am enjoying it immensely.

My project is(are) centered on generating Lotto Numbers for fun. Picking 5 random numbers that don't repeat was pretty easy.

So next I wanted to random generate numbers until 5 numbers from 1 to 70 were generated 10 times. Once that number was generated 10 times it would be my first lotto number and so on and so forth.

See my brutal caveman solution. It works, I just pick the first 5 from the printed list. And the first from the mega number list. But I'm looking for hints to "beautify" and or Pythony my solution.

Thx Much SpookyWatcher

10 MAJOR NUMBERS IN ARRAY

My task is : Perform a program that generates 100 random numbers (Between 0 and 100) by saving them in a vector. Then show the 10 majors. The repeated ones leave. What i did is :

public static void main (String[] args) {
    Random rnd=new Random();

    int [] vec=new int [10];
    int largest=vec[0];

    for (int i = 0; i < vec.length; i++)
        vec[i]=rnd.nextInt(100);

    for (int i = 0; i < vec.length; i++) {
        if (vec[i] > largest) {
            largest = vec[i];
        }   

        /*if (vec[i]>vec[0]){       
        System.out.print(vec[i]+" ");*/
        System.out.print(largest);  
    }
}
