大伙看看这个8和9，用eclipse怎么做啊，

public static void main(String[] args) {
        int value = 'X';
        System.out.println(value);

        float a1 = 100 / 30;
        int a2 = 100 / 30;
        int a3 = 100 % 30;
        System.out.println("100除以30的浮点数为：" + a1);
        System.out.println("100除以30的整数为：" + a2);
        System.out.println("100除以30的余数为：" + a3);
    }
