public final class Unchecked extends Object
Checked exceptions are one of Java's biggest flaws. Due to backwards-compatibility, we're inheriting all the checked exception trouble back from JDK 1.0. This becomes even more obvious when using lambda expressions, most of which are not allowed to throw checked exceptions.
This library tries to ease some pain and wraps / unwraps a variety of API elements from the JDK 8 to improve interoperability with checked exceptions.
