How to set test to failed

Hello everyone,

I have created following method

public static void testverify()
{
desktop.<RumbaTextField>find("/WPFWindow[@caption='Terminal - Micro Focus Rumba']//FormsHost//RumbaScreen//RumbaTextField[@priorlabel='Part']").setText("6151000");
desktop.<RumbaTextField>find("/WPFWindow[@caption='Terminal - Micro Focus Rumba']//FormsHost//RumbaScreen//RumbaTextField[@priorlabel='Group']").setText("20");
desktop.<RumbaTextField>find("/WPFWindow[@caption='Terminal - Micro Focus Rumba']//FormsHost//RumbaScreen//RumbaTextField[@priorlabel='Group'][2]").setText("1000");
desktop.<RumbaTextField>find("/WPFWindow[@caption='Terminal - Micro Focus Rumba']//FormsHost//RumbaScreen//RumbaTextField[@priorlabel='P/P']").sendKeys("@E");

RumbaLabel label = desktop.<RumbaLabel>find("/WPFWindow[@caption='Terminal - Micro Focus Rumba']//FormsHost//RumbaScreen//RumbaLabel[@caption='9404099']");
String Val = label.getProperty("caption").toString();

if (Val == "9404100")
{
System.out.println("Expected Result 9404100 " + "You got: " + Val);
}
else
{
System.out.println("Expected Result 9404100 " + "your result" + Val);
}
Assert.assertEquals("9404100", Val);
}

when i run the test case it indicates following:

With my method I want the test to fail.

How do I make it fail?

Thank you in advance

Regards
