Sum in Java

In Java, there are different ways to do this in Java depending on what the input type happens to be (e.g., integers, arrays, etc.). Here's four examples:

1. Sum of Two Integers

public class Main {
    public static void main(String[] args) {
        int num1 = 5;
        int num2 = 10;
        int sum = num1 + num2;
        System.out.println("Sum: " + sum);
    }
}

3. Sum of Two Floating Point Numbers:

public class Main {
    public static void main(String[] args) {
        int[] numbers = {1, 2, 3, 4, 5};
        int sum = 0;
        for (int num : numbers) {
            sum += num;
        }
        System.out.println("Sum of array: " + sum);
  }

3. Sum of Two Floating Point Numbers:

public class Main {
    public static void main(String[] args) {
        double num1 = 5.5;
        double num2 = 10.2;
        double sum = num1 + num2;
        System.out.println("Sum: " + sum);
    }
}

4. Sum of Numbers Using Java Streams (Java 8+):

import java.util.stream.IntStream;

public class Main {
    public static void main(String[] args) {
        int[] numbers = {1, 2, 3, 4, 5};
        int sum = IntStream.of(numbers).sum();
        System.out.println("Sum using streams: " + sum);
    }
}

These are some simple ways to calculate the sum in Java. Let me know if you need a specific implementation!
