Why are Runtime Exceptions “unchecked” in Java?

Question

Why does it make sense to have Runtime Exceptions UnChecked (as opposed to if they were Checked)?

Answer 1

This simply means that the compiler will not force you to look for an exception, but you can still throw it at runtime. As one benefit, this allows you to throw new exceptions from your classes without requiring you to alter your interface, causing callers to change their code.
