The Sample program code given below will test your knowledge of method overriding in Java.

Given below the sample code :

1   class A1{
2   public void process() { System.out.print("Inside A1 "); }}
3   class B extends A1{
4   public void process() throws IOException{
5   super.process();
6   System.out.print("Inside B ");
7   throw new IOException();
8   }
9   public static void main(String[] args){
10 try { new B().process(); }
11 catch (IOException e) { System.out.println("Exception is caught "); }}}

How can we correct the above code?
