public class Test01ArithmeticException {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        division(30, 3);
        division(30, 0);
    }

    public static void division(int a, int b) {
        System.out.println("计算除法");
        System.out.println("结果。。。" + a / b);
    }
}
