It seems like you're asking for a solution in an object-oriented programming language. Here's a simple example in Java:

```java
public class Student {
String name;
int marks;

// Constructor without arguments
public Student() {
this.name = "";
this.marks = 0;
}

// Constructor with arguments
public Student(String name, int marks) {
this.name = name;
this.marks = marks;
}

// Method to calculate result
public void calculateResult() {
if (this.marks 500) {
System.out.println("Pass");
} else {
System.out.println("Fail");
}
}

public static void main(String[] args) {
// Creating objects and entering details
Student student1 = new Student("John", 600);
Student student2 = new Student("Jane", 400);

// Calculating results
student1.calculateResult();
student2.calculateResult();
}
}
```

In this code, we have a `Student` class with two constructors - one without arguments and one with arguments. The `calculateResult` method checks if the student's marks are greater than 500 and prints "Pass" if they are, and "Fail" otherwise. In the `main` method, we create two `Student` objects and call the `calculateResult` method on each of them.
