Hi Friend,

Try the following code:

import java.util.*;
class RandomNumberExample {
static Random generator = new Random();
public static int get (int[] array) {
int rnd = generator.nextInt(array.length);
return array[rnd];
}
public static void main(String[]args){
int arr[]=new int[10];
Scanner input=new Scanner(System.in);
System.out.println("Enter 10 numbers: ");
for(int i=0;i<10;i++){
arr[i]=input.nextInt();
}
System.out.println();
System.out.println("Random numbers are: ");
int random[]=new int[5];
for(int i=0;i<random.length;i++){
random[i] = RandomNumberExample.get(arr);
System.out.println(random[i]);
}
}
}

Thanks
