|
|

|
### Instructions
|
||
|
|
|
||
|
|
Create a file `ListContains.java`.
|
||
|
|
|
||
|
|
Write a function `containsValue` that returns true if the list as parameter contains the element as parameter, false otherwise.
|
||
|
|
|
||
|
|
### Expected Functions
|
||
|
|
|
||
|
|
```java
|
||
|
|
import java.util.List;
|
||
|
|
|
||
|
|
public class ListContains {
|
||
|
|
public static boolean containsValue(List<Integer> list, Integer value) {
|
||
|
|
// your code here
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible ExerciseRunner.java to test your function :
|
||
|
|
|
||
|
|
```java
|
||
|
|
import java.util.List;
|
||
|
|
|
||
|
|
public class ExerciseRunner {
|
||
|
|
|
||
|
|
public static void main(String[] args) {
|
||
|
|
System.out.println(ListContains.containsValue(List.of(9, 13, 8, 23, 1, 0, 89), 8));
|
||
|
|
System.out.println(ListContains.containsValue(List.of(9, 13, 8, 23, 1, 0, 89), 10));
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
and its output :
|
||
|
|
|
||
|
|
```shell
|
||
|
|
$ javac *.java -d build
|
||
|
|
$ java -cp build ExerciseRunner
|
||
|
|
true
|
||
|
|
false
|
