# ArgumentCaptor

You can also get value of parameters of mocked methods, you can then Assert for their value.

Below is the same example of calculator class.

```java
// example statement
final int addition = calculator.getAddition(2, 3);

// Create captor
ArgumentCaptor<Integer> argumentCaptor = ArgumentCaptor.forClass(Integer.class);

Mockito.when(mckCalculator.getAddition(argumentCaptor.capture(), argumentCaptor.capture())).thenReturn(5);

final int firstNum = argumentCaptor.getValue();
Assert.assertEquals(2, firstNum);

// You can get second num by calling getAllValues()
final int secondNum = argumentCaptor.getAllValues()[1];
Assert.assertEquals(3, secondNum);
```
