Thread: Create non repeated words

Hello guys,
I wrote a code for a "skydiving" program that randomly selects the "maneuvers" to be performed by the skydiver during his skydive. I am almost done with the program. I just need to figure out how to print non repeated maneuvers for each round. Each round may not consist of two of the same maneuvers. The program that I wrote randomly picks the maneuvers but sometimes it still prints out two of the same maneuvers for each round. I have no clue how to do this. Any ideas? Thank you very much in advance.

The following is my code.

 
import java.util.Scanner;
import java.util.Random;
///v.0
public class Testpart2 {
 
 
 
	public static void main(String[] args) {
		Random randomNumbers=new Random();
		Scanner input = new Scanner(System.in);
		// TODO Auto-generated method stub
 
	int A;
	int count;
	int roundcount;
	roundcount=0;
 
 
String wordA = "2-Sidebody-Donut or INTER or Side Flake Donut,TEST:4-Monopod or INTER TEST:6-Stardian or INTER TEST :7-Sidebuddies or INTER TEST:9-Cat-Accordian or INTER TEST:15-Caterpilar or INTER TEST:19-Ritz or INTER or Icepick TEST:21-Zig-Zag or INTER or Margus TEST";
String[] wordAAsArray = wordA.split(":");/////Condition for class A
 
 
 
System.out.println(" How many rounds would you like to produce? - Enter 6 or 10");
count=input.nextInt();
 
System.out.println("");
 
System.out.println("Does your team belong to the class A, (1 for YES. 0 for NO)");/////////// A class
 
A = input.nextInt();
 
 
 
for (int i = 1; i <= count; i++)
{
	roundcount++;
	System.out.println("-------------------------Round " +roundcount);
	System.out.println();
if (A==1) /////Class A
		{
 
	System.out.println(" Your team shold perform the following dives (A-CLASS)!");
		System.out.println();
 
		{int index = new Random().nextInt(wordAAsArray.length);
		String random1Word = wordAAsArray[index];
		System.out.println("Dive #1 -A = " +random1Word);}
 
		{int index = new Random().nextInt(wordAAsArray.length);
		String random1Word = wordAAsArray[index];
		System.out.println("Dive #2-A = " +random1Word);}
 
		{int index = new Random().nextInt(wordAAsArray.length);
		String random1Word = wordAAsArray[index];
		System.out.println("Dive #3-A = " +random1Word);
 
		}
 
 
		}
 
}
	}
}

A set of objects can be a useful way to determine if an object has already been chosen. Choose an object and add it to the set. If the set accepts the object, then that object has not been previously chosen and added to the set. If the set does not accept the object, well, you can see the rest.
