## IntOperations
### Instructions
Create a file `IntOperation.java`.
Write a function `addTwoIntegers` that returns the sum of two integers passed as parameter.
Write a function `substractTwoIntegers` that returns subtraction of two integers passed as parameter.
Write a function `multiplyTwoIntegers` that returns the multiplication of two integers passed as parameter.
Write a function `divideTwoIntegers` that returns the Euclidian division of two integers passed as parameter. We ignore the divide by 0 case.
### Expected Functions
```java
public class IntOperation {
public static int addTwoIntegers(int a, int b) {
// your code here
}
public static int subtractTwoIntegers(int a, int b) {
// your code here
}
public static int multiplyTwoIntegers(int a, int b) {
// your code here
}
public static int divideTwoIntegers(int a, int b) {
// 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("Add");
System.out.println(IntOperation.addTwoIntegers(1, 2));
System.out.println(IntOperation.addTwoIntegers(15, 68));
System.out.println("Subtract");
System.out.println(IntOperation.subtractTwoIntegers(4, 1));
System.out.println(IntOperation.subtractTwoIntegers(10, 23));
System.out.println("Multiply");
System.out.println(IntOperation.multiplyTwoIntegers(3, 6));
System.out.println(IntOperation.multiplyTwoIntegers(12, 11));
System.out.println("Divide");
System.out.println(IntOperation.divideTwoIntegers(8, 2));
System.out.println(IntOperation.divideTwoIntegers(13, 4));
}
}
```
and its output :
```shell
$ javac *.java -d build
$ java -cp build ExerciseRunner
Add
