How do you test code that uses generics overview?

Testing code that uses generics in Java involves verifying that your generic classes and methods work correctly with different types of objects. One common approach is to create unit tests that utilize various type parameters to ensure that your generic implementations behave as expected. Below is an example of how to test a generic method using JUnit.

@Test public void testGenericMethod() { GenericClass stringInstance = new GenericClass<>(); stringInstance.add("Hello"); assertEquals("Hello", stringInstance.get(0)); GenericClass integerInstance = new GenericClass<>(); integerInstance.add(123); assertEquals(123, integerInstance.get(0)); }
