比如 获取 [1,100]

public static String getRandom(int min, int max){
    Random random = new Random();
    int s = random.nextInt(max) % (max - min + 1) + min;
    return String.valueOf(s);

}

public static String getRandom(int min, int max){
 Random random = new Random();
 int s = random.nextInt(1) % (100- 1+ 1) + 1;
 return String.valueOf(s);}
