Exception in thread “main” java.lang.IllegalArgumentException

Posted: May 9, 2012 in Java


It is the child class of Runtime Exception and it is unchecked. Thrown by programmer or API developer to indicate that a method has invoked with an illegal or in appropriate argument.

It is not JVM Exception.


public class Test {

 public static void main(String[] args) {

Thread.currentThread().setPriority(100);   ———-> here possible values are 1 to 10. (except 1 to 10 throws illegalArguementException)
