初学:请问是不是那里设置错了?

学习一段关于异常的代码如下:
public class TestException
{
        public static void main(String [] args)
        {
                try
                {
                        int reslut = new Test().devide( 3, 0 );
                        System.out.println("the result is" + reslut );
                }
                catch(Exception e)
                {
                        System.out.println(e.getMessage());
                }
                System.out.println("program is running here ,that is normal !";
        }
}
class Test
{
        public int devide(int x, int y)
        {
                int result = x/y;
                return x/y;
        }
}
编译错误为:
L:\java\Exception2.java:1: class TestException is public, should be declared in a file named TestException.java
public class TestException
       ^
L:\java\Exception.java:1: duplicate class: Test
class Test
^
L:\java\Exception.java:20: duplicate class: TestException
class TestException
^
L:\java\Exception2.java:10: cannot access Exception
bad class file: L:\java\Exception.java
file does not contain class Exception
Please remove or make sure it appears in the correct subdirectory of the classpath.
                catch(Exception e)
                      ^
4 errors

请问是那里出了问题?

:\java\Exception2.java:1: class TestException is public, should be declared in a file named TestException.java
public class TestException

把文件名改为TestException.java，文件名必须与声明为public的类的名字相同
