  Checked Exception: You must have to handle those exceptions by yourself using try-catch or throws clause
  Unckecked: JRE will take care of these things
  
  Why Checked Exception: In case of IOException, for example you wrote a program to read a file. How can java know if file is there to read? that is why it insist you to catch this exception by yourself.
  Java is telling you that somewhere it could be wrong.
  
  Rest, explaining each exception will be a theory , I would suggest you to write programs in which these exception can occur. If will give you live practical example.

  for example:
  
  
  ArithmeticException:
  
  Error program:
  
  class ArithException
  {
  public static void main(String arg[])
  {
  System.out.println(2/0);
  }
  }
  
  Output: ArithmeticException Error.
  
  
  Correction Program:
  
  class ArithException
  {
  public static void main(String arg[])
  {
  try{
  System.out.println(2/0);
  }catch(ArithmeticException)
  { System.out.println("divide by zero is not valued");
  }
  }
  
  Ouptut: Divide by zero is not Valued.
  
  
  I need like this for every exception.
  
  would you help me?
