### val - Final Local Variables
7

8
```java { .api }
9
public final class val {
10
    private val() {}
11
}
12
```
13

14
### var - Mutable Local Variables
15

16
```java { .api }
17
public final class var {
18
    private var() {}
19
}
20
```

22
**Usage Examples:**
23

24
```java
25
import lombok.val;
26
import lombok.var;
27

28
public class Example {
29
    public void demonstrateTypeInference() {
30
        val name = "John Doe";  // final String name = "John Doe";
31
        val age = 30;           // final int age = 30;
32
        val users = new ArrayList<User>();  // final ArrayList<User> users = ...
33
        
34
        var counter = 0;        // int counter = 0;
35
        var message = "Hello";  // String message = "Hello";
36
        
37
        counter++; // OK - var is mutable
38
        // name = "Jane"; // Compilation error - val is final
39
    }
40
}
