关于异常的一段问题代码求解决 - 黑马程序员技术交流社区

package Exception;
class FuShuException extends Exception{
FuShuException(String msg){
super(msg);
}
}
class Demo4{
int div (int a,int b) throws FuShuException{
if(b<0){
throw new FuShuException("除数为负数");
}
return a/b;
}
}
public class ExceptionDemo4 {
public static void main(String[] args) {
// TODO Auto-generated method stub
Demo4 d = new Demo4();
try{
int x = d.div(4, -1);
}
catch(FuShuException e){
System.out.println(e.toString());
}
finally{
System.out.println("finally");//finally中存在的是一定会被执行的代码。
}
System.out.println("ocer");
}
}
在eclipse中报错：
finally
Exception in thread "main" java.lang.NoSuchMethodError: Exception.FuShuException: method <init>(Ljava/lang/String;)V not found
at Exception.Demo4.div(ExceptionDemo4.java:11)
at Exception.ExceptionDemo4.main(ExceptionDemo4.java:24)
