Returns the same hash code for the given object as would be returned by the default method hashCode(), whether or not the given object's class overrides hashCode().

Usage

From source file:nz.co.senanque.forms.FormFactoryTest.java

@Test
public void testGetForm() {
    WorkflowForm form1 = m_formFactory.getForm("launchForm");
    WorkflowForm form2 = m_formFactory.getForm("launchForm");
    assertFalse(System.identityHashCode(form2) == System.identityHashCode(form1));
    WorkflowForm form3 = m_formFactory.getForm("secondForm");
    assertNotNull(form3);//from   w w  w.j  av a  2  s.c o  m
}

From source file:com.mycompany.sportsclubimmutable.PlayerRecords.testRuns.java

@Test //
public void testImmutable() {
    //Testing that the object wasn't edited or changed but that
    //A whole new object was created and returned

    bts_runs = new Batsman_runs("Rafiq", "Samsodien", 5, 50);

    /********  Get  HashCode   *****************/
    String num1 = Integer.toHexString(System.identityHashCode(bts_runs));

    String num2 = Integer.toHexString(System.identityHashCode(bts_runs.updateGamesPlayed(7)));

    Assert.assertNotEquals(num1, num2, "Objects are same");
}
