用JAVA来寻找和打印素数

public static void main(String[] args) {
		for (int i = 2; i < 100; i++) {
			int factors = 0;
			for (int j = 1; j < (i + 2) / 2; j++) {
				if ((i % j) == 0)
					factors++;
			}
			if (factors < 2)
				System.out.println(i + " is prime");
		}

	}

谢谢,我原本不会打,现在理解了,从中学到了用factors++,这种方法
