Sure, I can help you with that! Here's an example of Java code that includes a main method and a separate second method with arguments:
```java
public class Example {
public static void main(String[] args) {
int num1 = 5;
int num2 = 10;
// Calling the second method and passing arguments
int result = calculateSum(num1, num2);
System.out.println("The sum is: " + result);
}
// Second method to calculate the sum
public static int calculateSum(int a, int b) {
int sum = a + b;
return sum;
}
}
```
In this example, we have a main method where we declare two integer variables `num1` and `num2`. We then call the second method `calculateSum` and pass the values of `num1` and `num2` as arguments. The second method takes in two integer parameters `a` and `b`, calculates their sum, and returns the result. Finally, in the main method, we print the result.
Feel free to modify the code according to your needs or add more functionality to the second method. Let me know if you have any questions!
