编写了一个异常类，在编译时出现了异常？该怎么解决？
class Test
{
public int devide(int x,int y) throws ArithmeticException,DevideByMinusException
{
if(y<0)
throw new DevideByMinusException("devisor is"+y);
int result = x/y;
return result;
}
}
class DevideByMinusException extends Exception
{
public DevideByMinusException(String mess)
{
super(mess);
}
}
class TestException
{
public static void main(String [] args)
{
try
{
new Test().devide(3,-1);
}
catch(ArithmeticException e)
{
System.out.println("program is running into ArithMetic");
e.printStackTrace();
}
catch(DevideByMinusException e)
{
System.out.println("program is running into DevideByMinus");
e.printStackTrace();
}
catch(Exception ex)
{
System.out.println(ex.getMessage());
}
finally
{
System.out.println("close the files");
}
System.out.println("program is running here!");
}
}
在我的机器上运行的结果是这样的：
.\Exception.java:1: duplicate class: Test
class Test
^
.\Exception.java:12: duplicate class: DevideByMinusException
class DevideByMinusException extends Exception

.\Exception.java:19: duplicate class: TestException

file does not contain class Exception
Please remove or make sure it appears in the correct subdirectory of the classpa

----------------解决方案--------------------------------------------------------
你定义了重复的类
----------------解决方案--------------------------------------------------------
program is running into DevideByMinus
DevideByMinusException: devisor is-1
at Test.devide(TestException.java:6)
at TestException.main(TestException.java:25)
close the files
program is running here!
Press any key to continue...
这是在我的电脑上运行的 和你的差好多哦 看是你要得效果吗

对呀，这是我设计该类，所要到的结果。
可是我的怎么就出现了
.\Exception.java:1: duplicate class: Test
class Test
^
.\Exception.java:12: duplicate class: DevideByMinusException
class DevideByMinusException extends Exception
^
.\Exception.java:19: duplicate class: TestException

bad class file: .\Exception.java
file does not contain class Exception
Please remove or make sure it appears in the correct subdirectory of the classpa
th.
class DevideByMinusException extends Exception

4 errors
这个结果呢。
郁闷！！！

你肯定是一个文件里面包含了名字重复的类
----------------解决方案--------------------------------------------------------
我的文件名是Exception.java。
文件的名字与java里保留字有关系吗？
