Trouble with random initialization

I'm currently working on a java project for a class in uni. One of the methods I must complete asks me to fill an Array with random numbers, but the array type is from a class called Weapon. I can't convert my type to integers so the compiler says that Weapons cannot be converted to integers.

I've tried searching for a solution, even writing a method called nextWeapon(), but as I just started learning programming, it seems to be a bit diffuclt.

    int W;
    Weapon[] weapons = new Weapon[W];

    public Weapon[] createRandomWeapon(){

    Random rand = new Random();
    for(int i = 0; i < weapons.length; i++){
        weapons[i] = rand.nextInt();
    }
    return weapons;
}
