现在有10个随机数，随机数的范围在1到100之间。现在要求写出一种算法，将1到100之间没有在随机数中的数求出来

package test;
import java.util.Random;
public class TestRandom {
	public static void main(String[] args) {
		test();
	}
	
	static void test(){
		int[] randomNums = new int[10];
        Random random = new Random();
        for (int i = 0, length = randomNums.length; i < length; i++) {
            randomNums[i] = random.nextInt(100);
        }
        long start = System.currentTimeMillis();
        boolean[] bitArray = new boolean[100];
        for (int i = 0, length = randomNums.length; i < length; i++) {
            bitArray[randomNums[i]] = true;
        }
        for (int i = 0, length = bitArray.length; i < length; i++) {
            if (bitArray[i]) {
                continue;
            }else{
            	System.out.println(i);
            }
        }
        long end = System.currentTimeMillis();
        System.out.println("Spend milliseconds: " + (end - start));
	}
}
