   public static void main(String[] args) {

       Scanner scan=new Scanner(System.in);

       System.out.println("Enter marks in Maths");

       int num1=scan.nextInt();

       System.out.println("Enter marks in English");

       int num2=scan.nextInt();

       System.out.println("Enter marks in Science");

       int num3=scan.nextInt();

       System.out.println("Enter marks in Hindi");

       int num4=scan.nextInt();

       System.out.println("Enter marks in S.St");

       int num5=scan.nextInt();

       System.out.println("Enter marks in Computer");

       int num6=scan.nextInt();

       int total=num1+num2+num3+num4+num5+num6;

       double average=(double)total/3;

       double percentage=(double)total/6;

       System.out.println("Total marks:"+total+"\naverage:"+average+"\npercentage:"+percentage);

   }

}

Write a program to enter marks of all subjects and compute total, average and percentage.

$\star\:\:\:\sf\large\underline\blue{Solution:-}$

import java.util.*;

class Program

{

public static void main(String s[])

{

Scanner sc = new Scanner(System.in);

System.out.print("How many Subjects? ");

int n=sc.nextInt();

System.out.println("Enter the marks....");

double marks, s=0,av=0,p=0;

for(int i=1;i<=n;i++)

{

System.out.print("Enter: ");

marks=sc.nextDouble();

s+=marks;

}

av=s/(double)n;

p=s/(double)n * 100.0;

System.out.println("Total marks: "+s);

System.out.println("Average marks: "+av);

System.out.println("Percentage: "+p);

}

}
