throwing Exception

I want to throw exception manually. I tried the following but it fails.

Code:

---

throw java.lang.ArrayIndexOutOfBoundsException;

---

I get following exception:

Code:

---

Exception in thread "main" java.lang.Error: Unresolved compilation problem:
        java.lang.ArrayIndexOutOfBoundsException cannot be resolved

---

Please advice.

What does your method signature look like?

Code:

---

public void calculateSum()
{
...
}

---

Actually method has nothing to do with this. I want to know, can I raise an exception myself?

Yes. You just have to put 'throws whateverException' on the end of your signature.

Code:

---

public void calculateSum() throws InvalidSumException{

}
