+
+## Tasks
+1. Create a class called `Student` with:
+   - `String name`
+   - `int rollNumber`
+   - `char grade`
+
+2. Create a method `displayDetails()` in the `Student` class that prints student information.
+
+3. In `Main.java`, create a `Student` object, assign sample data, and call `displayDetails()`.
+
+## Submission Instructions
