While overriding can the subclass choose not to throw an exception in java?
If the super-class method throws certain exception, you can override it without throwing any exception.
Example
In the following example the sampleMethod() method of the super-class throws FileNotFoundException exception and, the sampleMethod() method does not throw any exception at all. Still this program gets compiled and executed without any errors.
import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.util.Scanner;
abstract class Super {
public void sampleMethod()throws FileNotFoundException {
System.out.println("Method of superclass");
}
}
public class ExceptionsExample extends Super {
public void sampleMethod() {
System.out.println("Method of Subclass");
}
public static void main(String args[]) {
ExceptionsExample obj = new ExceptionsExample();
obj.sampleMethod();
}
}Output
Method of Subclass
