Exceptions in method signature

[Akhilesh Trivedi]

Does method 'signature' includes or excludes exceptions?

[John Jai]

From the JLS

8.4.2 Method Signature

The signature of a method consists of the name of the method and the number and types of formal parameters to the method. A class may not declare two methods with the same signature, or a compile-time error occurs.

[Matthew Brown]

If the signature included exceptions, you'd be able to do this without a compiler error because the two methods would have different signatures:

class Test {
    void doSomething() {...}
    void doSomething() throws IOException {...}
}

Thanks John and Mathew!
