How to generate unique Random positive integers between two given numbers and all the numbers between two given numbers should be present.

Its like jumbling the numbers between 1 to 1000.

public class MyTest {
    public static void main(String args[]) {
        new MyTest().doit();
    }
    public void doit() {
      // no seed
      java.util.Random rand = new java.util.Random();
 //SEEDED
 // long seed = 10;  //I'd get this from data/time
      //Random rand  = new Random(seed);
      // random integer 0 to 10
      int max = 10;
      for (int i=0; i<10; i++) {
          System.out.println(rand.nextInt(max + 1));
      }
      // random double 0 to 10
      double maxd = 10;
      for (int i=0; i<10; i++) {
        System.out.println(maxd * rand.nextDouble());
        }
    }
}
 

public class MyTest {
    public static void main(String args[]) {
        new MyTest().doit();
    }
    public void doit() {
      java.util.Random rand = new java.util.Random();
      // random integer 0 to 10
      int max = 10;
      for (int i=0; i<10; i++) {
          System.out.println(rand.nextInt(max + 1));
      }
      // random double 0 to 10
      double maxd = 10;
      for (int i=0; i<10; i++) {
        System.out.println(maxd * rand.nextDouble());
        }
    }
}
