+## JAVA Implementation
+
+```java
+
+public class EvenCheck {
+    // Method to check if a number is even
+    public static boolean isEven(int number) {
+        return number % 2 == 0;
+    }
+
+    // Main method for running the program
+    public static void main(String[] args) {
+        System.out.println(isEven(4)); // Output: true
+        System.out.println(isEven(7)); // Output: false
+    }
+}
+```
+
+
+## C++ Implementation
+#include <iostream>
+using namespace std;
+
+```
+
+// Function to check if a number is even
+bool isEven(int number) {
+    return number % 2 == 0;
+}
+
+int main() {
+
+    cout << isEven(4) << endl;  // Output: 1 (true)
+    cout << isEven(7) << endl;  // Output: 0 (false)
+    return 0;
+}
+
+```

+## Explanation  
+
+First I want to talk about a prime number. A prime number is a natural number only divisible by 1 and its self.
+
+Implementing it into code;
+
+
+The "Java" implementation uses a function named called IsPrime. This Method needs a number as an imput and checks if its prime. The first being if the number is less than or equal to 1. If the results arent a prime number the method is false. However it runs a loop starting from 2 to the sqrt of the number. Being that if the number is divisible by anything in that range the meothod will be false. if no divide then method is true.
+
+
+The "C++" Implementation also uses the function IsPrime. This function also works in a simimlar way then java. In thid method you need to first check if the number is 1 or less than, which returns false in that sense. After, the function literally loops from 2 up to the sqrt of the number simlar to java, looking for nay divisors. If i does find a divide then this method will return false. Concluding that if no divisor was found then menthod remains true.

+|-----------------------|-----------------------------------------------|-----------------------------------------------|
+| **Syntax**            | Both programs usse a function with a simlilar purpose       | Java uses "IsPrime" as C++ uses "isPrime" but written out differently.|
+| **Input**             | Both take number input to check if output is prime.                           | Java has a personal writting style while C++ follows an ordered structure.|
+| **Main Function**     | Both have main start section to run code.                        | Java uses "public static void Main()" C++ uses "int main()" to start.|
+| **First Line of Code** | Both need a special line including designated tools for code to start and run. | Java starts with "public class;". C++ starts with "#include <iostream>"|
+| **Printing Output**    | Both Java and C++ use printing outputs to show if number is prime.          | Java uses "System.out.print()". C++ uses "cout" but, for larger programs uses std::cout to avoid potential name conflicts.|
