java 用的最多的异常处理
1 class Math{
2 public int div(int i,int j) throws Exception{
3 System.out.println("========计算开始=======");
4 int temp=0;
5 try{
6 temp=i%j;
7 } catch(Exception e){
8 throw e;
9 } finally{
10 System.out.println("==========计算结束=======");
11 }
12 return temp;
13 }
14 }
15 public class ThrowsDemo {
16 public static void main(String args[]) throws Exception{
17 Math m=new Math();
18 try{
19 System.out.println("除法操作："+m.div(10,0));
20 }catch (Exception e){
21 System.out.println("异常产生："+e);
22 }
23 }
24 }
