I'm trying to create an int list with 5 random numbers each one up to 10

Answer 1

public class random
{
public static void main(String args[])
{
int i,n;
for(i=1;i<=5;i++)//as you want 5 random no.s
{
n=(int)((Math.random()*(10-1))+1);
System.out.println(n);
}
}
}

Answer 2

import java.util.*;
Random rnd=new Random();
int[] arr=new int[5];
for(int i=0;i<5;i++)
arr[i] = rnd.nextInt(10) +1;
List<Integer> lt= new ArrayList<Integer>();
for(int z:arr)
lt.add(z);

Have you imported collections and random class?

Answer 10

Im new to this, so im not really sure. I imported all in java util with the sentex "import java.util*;"

Is this not how you import these classes as well? I thought if you use the asterisk, you're importing these classes as well.

Answer 11

yes, import java.util.*;

Answer 12

Yea i used that but was still unsuccessfull

Answer 13

@Anthony, There are 2 types of list.
import java.awt.List;
and
import java.util.List;

You need second one.
So use,
import java.util.List;
import java.util.Random;
