## StringConcat
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
Create a file `StringConcat.java`.
|
||
|
|
|
||
|
|
Write a function `concat` that returns the concatenation of the two strings passed as parameters.
|
||
|
|
|
||
|
|
### Expected Functions
|
||
|
|
|
||
|
|
```java
|
||
|
|
public class StringConcat {
|
||
|
|
public static String concat(String s1, String s2) {
|
||
|
|
// your code here
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a possible ExerciseRunner.java to test your function :
|
||
|
|
|
||
|
|
```java
|
||
|
|
public class ExerciseRunner {
|
||
|
|
public static void main(String[] args) {
|
||
|
|
System.out.println(StringConcat.concat("Hello ", "étudiant !"));
|
||
|
|
System.out.println(StringConcat.concat("", "Hello World !"));
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
and its output :
|
||
|
|
|
||
|
|
```shell
|
||
|
|
$ javac *.java -d build
|
||
|
|
$ java -cp build ExerciseRunner
|
||
|
|
Hello étudiant !
|
||
|
|
Hello World !
|
||
|
|
$
|
||
|
|
```
