Second.java:10: test() in Second cannot implement test() in TestInterface; overridden method does not throw java.io.IOException
public void test() throws IOException
^
1 error
The overriding method may choose to NOT throw an exception that is thrown by the overridden method.
ReplyDeleteE.g.:
interface TestInterface
{
void test() throws IOException;
}
public class Second implements TestInterface
{
public void test()
{
// Overriding method not
// throwing IOException
.. // Perfectly fine.
}
}
