Q. write a java program A school conducts three exams namely term 1 exams,term 2 exams and final term exams. Final marks scored(weighted marks) are computed as 30% of term1 and term2 each’s marks + 40% of the final term marks. Write a program to compute the weighted marks for a student who scored 412 in first term, 423 in second term and 430 in third term. Then compute the weighted percentage out of 500 marks. Use appropriate constructor functions.
Answers
Answer:
This program calculates the grade of a student based on the marks entered by user in each subject. Program prints the grade based on this logic.
If the average of marks is >= 80 then prints Grade ‘A’
If the average is <80 and >=60 then prints Grade ‘B’
If the average is <60 and >=40 then prints Grade ‘C’
else prints Grade ‘D’
Explanation:
import java.util.Scanner;
public class JavaExample
{
public static void main(String args[])
{
/* This program assumes that the student has 6 subjects,
* thats why I have created the array of size 6. You can
* change this as per the requirement.
*/
int marks[] = new int[6];
int i;
float total=0, avg;
Scanner scanner = new Scanner(System.in);
for(i=0; i<6; i++) {
System.out.print("Enter Marks of Subject"+(i+1)+":");
marks[i] = scanner.nextInt();
total = total + marks[i];
}
scanner.close();
//Calculating average here
avg = total/6;
System.out.print("The student Grade is: ");
if(avg>=80)
{
System.out.print("A");
}
else if(avg>=60 && avg<80)
{
System.out.print("B");
}
else if(avg>=40 && avg<60)
{
System.out.print("C");
}
else
{
System.out.print("D");
}
}
}
