How to Assert No exception thrown TestNG java

Question

Hey All I have a question that I try to resolve. I am using selenium with pure java and test NG. In the test class I want to call a method and if the method throw exception I want to fail the test. this is the method:

public  void insertAddress2(String address2) throws Exception {}

and i want to call it from a test class, and if it (the insert address2 method) throw exception I want the test to fail.

this is the the class test Assertion statement

@Test(groups = {"address"},enabled = true)
public void testAddress() throws Exception {
Assert.assertNotEquals(adderess.insertAddress2("test"),ErrorMessagePermission, "");
}

can someone please advise what is the syntax and how to test not exception thrown in the insertAddress2 method from different class

Basically, even in tests, when you want to react on exceptions, you would have to catch them:

@Test(groups = {"address"}, enabled = true)
public void testAddress() { //no throws decleration required
    try {
        adderess.insertAddress2("test");
    } catch (Exception ex) {
        Assert.fail("Exception was thrown!");
    }
}
