+## Explanation
+
+The java implementation uses the counting system to only count to 2, to signify a prime number.
+
+The basic implementation also uses the counting system to only count to 2, to signify a prime number.
+
+### Differences
+
+1. **Syntax**: 
+   - In Java, it uses the fuctions Modelo function to determine if the reminder is zero to determine if the number is divisable evenly.
+   - Basic uses the if then else function to determine if the number is prime or not.
+
+3. **Function Calls**:
+   - The ability to print for both programs are different, java uses System.out.println, while BASIC just uses the word print.
