Exception Handling

int a = 100, b = 0;
int c = a/b;

class MyException extends Exception 
{
  public void method() throws XXXX
  {
    throw new MyException(); 
  }
}

try
{
  int arr[]={1,2};
  arr[2]=3/0;
  System.out.println(a[0]);         
}
catch(Exception e)
{
  System.out.println("Exception");
}
catch(ArithmeticException e)
{
  System.out.println("Divide by Zero");
}

public class test 
{
  static void method(){} 
  public static void main(String []args) throws Exception
  {
   try
   {
      method();
      System.out.println("try");
   }
   catch(Exception e)
   {
      System.out.println("catch");
   }
   finally
   {
      System.out.println("finally");
   }     
  }
}

import java.io.*;
class Super
{
 void show() 
 { System.out.println("parent"); }
}

public class Sub extends Super 
{
  void show() throws IOException		
  { System.out.println("child"); } 

  public static void main( String[] args )
  {
    Super s = new Sub();
    s.show();
  }  
}

If Super class method throws an exception, then Subclass overriden method .......
