Question

JAVA Program

The grade of the student for the Advanced Java course consists of 4 results: home task 1 (max 10 marks), home task 2 (max 10 marks), midterm test (max 30 marks) and examination (max 50 marks).

Write a JAVA program which does the following operations:

1. Asks user to input the name of the student and create a file called StudentName_JavaResults.txt, ex: MaryJohnson_JavaResults.txt

2. Asks user to input the results for home task 1, home task 2, midterm test, and examination (one by one). Save all these results to the file created in the previous part. The information in file should be readable and understandable.

3. Add logic to check, that home task 1 result is max 10 marks, home task 2 result is max 10 marks, midterm test result is max 30 marks, and examination - max 50 marks. If it is not, ask it again.

4.  Calculate the amount of marks gained during the course. Save this value to the file.

Code

import java.io.*;
import java.util.Scanner;
public class Main
{
public static void main(String[] args) throws IOException
{
Scanner input=new Scanner(System.in);
String fileName;
System.out.print("Enter name of student: ");
fileName=input.next();
fileName+="_JavaResults.txt";
FileWriter fileWriter = new FileWriter(fileName);
PrintWriter printWriter = new PrintWriter(fileWriter);
int homeTask1,homeTask2,midterm,examination;
  
while(true)
{
System.out.print("Enter the marks of the home task1 : ");
homeTask1=input.nextInt();
if(homeTask1>=1 && homeTask1<=10)
break;
else
System.out.println("Enter the marks between 1 and 10 inclusive.");
}
System.out.println();
while(true)
{
System.out.print("Enter the marks of the home task2 : ");
homeTask2=input.nextInt();
if(homeTask2>=1 && homeTask2<=10)
break;
else
System.out.println("Enter the marks between 1 and 10 inclusive.");
}
System.out.println();
while(true)
{
System.out.print("Enter the marks of the midterm : ");
midterm=input.nextInt();
if(midterm>=1 && midterm<=30)
break;
else
System.out.println("Enter the marks between 1 and 30 inclusive.");
}
System.out.println();
while(true)
{
System.out.print("Enter the marks of the Examination : ");
examination=input.nextInt();
if(examination>=1 && examination<=50)
break;
else
System.out.println("Enter the marks between 1 and 10 inclusive.");
}
System.out.println();
int sum=homeTask1+homeTask2+midterm+examination;
printWriter.printf("Home Task 1: %d%n",homeTask1);
printWriter.printf("Home Task 1: %d%n",homeTask2);
printWriter.printf("Midterm: %d%n",midterm);
printWriter.printf("Home Examination: %d%n",examination);
printWriter.printf("Total marks for Advanced Java course: %d%n",sum);
printWriter.close();
}
  
}
