An implementation of a method need not throw all exceptions thrown by the interface

import java.io.IOException;

 

interface TestInterface

{

        void test() throws IOException;

}

 

public class Second implements TestInterface

{

        public void test() // DOES NOT THROW IOEXCEPTION

        {

                System.out.println("Second.test() invoked");

        }

 

        public static void main(String[] args) throws IOException

        {

                TestInterface j = new Second();

                j.test();

        }

}
