避免在不同的函数中生成随机整数

My function:

public int[] generateRandomInteger(){
    int[] arr = new int[100];
    Random randomGenerator = new Random();

    for (int i = 0; i < 100; i++){
        int randomInt = randomGenerator.nextInt(16) + 10;
        arr[i] = randomInt;
    }        
    return arr;
}
public int[] generateRandomInteg
