java.lang.IllegalArgumentException Division by zero. You can also identify an IllegalArgumentException by its position in the exception hierarchy. As shown in the previous section, IllegalArgumentException is a subclass of RuntimeException, so it will be caught by a catch block that handles RuntimeException or any of its subclasses.

Learn how to construct and use an IllegalArgumentException, a runtime exception thrown when a method receives an illegal or inappropriate argument. See the constructors, methods, and inherited members of this class.

Learn what an IllegalArgumentException is, when it is thrown, and how to handle it in Java. See the constructors, methods, and an example of this runtime exception.

Throw and Resolve IllegalArgumentException in Java Use Try and Catch to Determine IllegalArgumentException With Scanner in Java This tutorial will classify the exception hierarchy by showing the java.lang.IllegalArgumentException class from the java.lang.object class. After that, we will execute three Java coding blocks to demonstrate

Leverage Java's Built-in Objects' Methods Many built-in Java objects, like Objects.requireNonNull, are designed to automatically throw IllegalArgumentException or related exceptions under certain conditions. Make use of these to simplify your validation

The end user cannot see private state so loosely speaking it takes precedence over IllegalArgumentException in the case where the client call has no way to know the object's state is inconsistent.
