Is it possible to arbitrarily throw an object of type Throwable in Java code?

In Java, you can throw any object that is a subclass of Throwable. However, in practice, objects of type Exception or Error are more commonly thrown.

Important:

• Throwable is the base class for all errors and exceptions.
• You can write throw new Throwable();, but this is not recommended because Throwable is too general.
• The compiler requires that checked exceptions, which are not subclasses of RuntimeException or Error, be declared in throws or handled.

Example:

throw new Throwable("Some throwable"); // technically possible, but not recommended

throw new Exception("Checked exception"); // must declare throws or handle

throw new RuntimeException("Unchecked exception"); // can be thrown without declaration
