Assertions are used mostly in JUnit or other testing tools, to check/assert test results. So it might give false impression to other developers that your method is a test method. Also it makes sense to throw IllegalArgumentException when a method has been passed an illegal or inappropriate argument.

Answer: Here is a java example of a method that throws an IllegalArgumentException: Source: (Example.java) public class Example { public static void main (String [] args) { method (-1);} public static void method (int x) {if (x < 0) {throw new IllegalArgumentException ("must be positive");}}} It’s because programs typically cannot be recovered from unchecked exceptions. Note that unchecked exceptions are subtypes of RuntimeException, although it is a subtype of Exception. For example, the following method does not have to declare to throw IllegalArgumentException which is an unchecked exception: An exception that occurs during the execution of a program is called an unchecked or a runtime exception. The main cause of unchecked exceptions is mostly due to programming errors like attempting to access an element with an invalid index, calling the method with illegal arguments, etc. I have some code code splits a string (user input) into an array and passes the elements of that array into a method as arguments.

unchecked or unsafe operations.
