Student Report Card System

[Pankaj-Str]

Objective

Create a Java application that accepts student details and their marks in various subjects, calculates the total and percentage, determines the pass/fail status, and assigns grades if the student passes. The application should handle input and output operations effectively and display the results in a formatted manner.

Requirements

Input Section

1. Student Details:

   • Name
   • Roll Number

2. Marks:

   • JAVA
   • C++
   • Go
   • Ruby
   • C#
   • Python

Output Section

1. Display the marks for each subject.
2. Calculate and display the total marks and percentage.
3. Determine and display the pass/fail status based on the percentage.
4. If the student passes, display the grade according to the grading system.

Grading System

• 80 - 100: Grade A
• 60 - 80: Grade B
• 40 - 60: Grade C
• 30 - 40: Grade D

Pass/Fail Criteria

• A student must have a minimum percentage of 40% to pass.

Instructions

1. Create a Student class to store the student's name, roll number, and marks for each subject.
2. Create methods for calculating total marks, percentage, and determining the pass/fail status.
3. Create methods for assigning grades if the student passes.
4. Implement input validation to ensure marks are between 0 and 100.

Example

Input

Enter your name: Nishant
Enter Your Roll Number: A1023

Enter Your JAVA Marks: 50
Enter Your C++ Marks: 20
Enter Your Go Marks: 25
Enter Your Ruby Marks: 96
Enter Your C# Marks: 70
Enter Your Python Marks: 65

Output

Student Report Card
-------------------
Name: Nishant 
Roll Number: A1023

Marks:
JAVA = 50/100 
C++ = 20/100 F
Go = 25/100 F
Ruby = 96/100
C# = 70/100
Python = 65/100

Total = 326/600
Percentage = 54%
Status: FAIL

Grading System (if passed):
80 - 100 = Grade A
60 - 80 = Grade B
40 - 60 = Grade C
30 - 40 = Grade D

Assignment Submission

Submit the Java source code file along with a document explaining the implementation, including how the input validation was handled and how the grading system was implemented.
