Exception Handling

Nested Exceptions

When a try catch block is present in another try block then it is called the nested try catch block.
Each time a try block does not have a catch handler for a particular exception, then the catch blocks of parent try block are inspected for that exception, if match is found that that catch block executes.

#Example

class demo
 {
    public static void main(String args[])
    {
      try
      {
        try
		{
        	System.out.println(5/0);
    	}
        catch(ArithmeticException err)
		{
        	System.out.print("Arithmetic Exception");
       	}
      }
      catch(ArrayIndexOutOfBoundsException err)
	  {
    	System.out.print("ArrayIndexOutOfBoundsException");
      }
    }
 }

Arithmetic Exception

#Example

 class demo
 {
    public static void main(String args[])
    {
      try
      {
        try
		{
		    int arr[]={2,5,6,1,0};
            System.out.println(arr[10]);
        }
        catch(ArithmeticException err)
		{
          	System.out.print("Arithmetic Exception");
    	}
      }
      catch(ArrayIndexOutOfBoundsException err)
	  {
    	System.out.print("ArrayIndexOutOfBounds Exception");
      }
  }
 }
