java自定義異常類===代碼問(wèn)題
代碼：
package?yichang;
public?class?Nuli{
?public?static?void?main(String[]?args){
??Nuli?one?=?new?Nuli();
??
??try{
???one.shuchu();
??}catch(Xinde?e){
???System.out.println("123");
???e.printStackTrace();
??}
?}
?public?void?shuchu()?throws?Xinde{
??int?a?=?10;
??int?b?=?0;
??if(a?==?10){
???a?=?a/b;
??}
?}
}自定義異常類：
package yichang;
public class Xinde extends Exception {
? public Xinde(String me){
?? super(me);
? }
}
其它都正常，就是不輸出? 123，哪位大神幫忙看看，謝謝了

// TODO Auto-generated method stub
show mo=new show();
try{
mo.show1();
}catch(Exception e){
System.out.println("輸出異常123");
e.printStackTrace();
}
}
public void show1() throws Exception{
int a=10;
int b=0;
if(a==10){
a=a/b;
}
}
}
