I've started to study JavaFX since a few day and I've figured out that Integer class is really java.lang.Integer reading this table. But why doesn't this code compile?
def num = new Integer(5);

I'm studying Exception Handling but i don't understand what happen in this code:
public class Test { public static void test() throws ArrayStoreException, ArithmeticException, InterruptedException { try { //... try { //... try { //... } finally { System.out.println("inner-inner-finally"); throw new InterruptedException(); } } finally { System.out.println("inner-finally"); throw new ArrayStoreException(); } } finally { System.out.println("finally"); throw new ArithmeticException(); } } public static void main(String[] args) { try { test(); } catch (ArrayStoreException e) { System.out.println("main -> exception: ArrayStoreException"); } catch (InterruptedException e) { System.out.println("main -> exception: InterruptedException"); } catch (ArithmeticException e) { System.out.println("main -> exception: ArithmeticException"); } } } //output: /* inner-inner-finally * inner-finally * finally * main -> exception: ArithmeticException */i wrote it to understand what happen when there are nested try block but i don't understand why InterruptedExcetion and ArrayStoreException aren't catched.

If i define the inner class when throw it, can i explain that it extend Throwable, Exception, RuntimeException or any other exception class?

Try to compile it using "javac -d E:\AqanTech\WebApp1\WEB-INF\classes\ *.java" while you are in E:\AqanTech\WebApp1\WEB-INF\src.

Hi all.

I'm studying inner class and i don't understand why it isn't possible throw an anonymous inner class like following exemple:
throw new AnonymousInnerClass() { //class body };
