Logic:- First we will ask the user for the total number of the subject after that we will enter marks of all those subjects. Now we will calculate a percentage of marks and print student marks, percentage, and Grade of Student. Percentage formula is given Below. 

Percentage of Marks = (all subject marks sum) / Total Subject *100.

Now next step to add or find a sum of all subjects marks entered by the user and apply the formula and print the output calculated by the formula given.


System.out.print("Enter The 5 Subject Marks : ");

for(i=0; i<5; i++)
{
marks[i] = sc.nextInt();
sum = sum + marks[i];
}

System.out.print("\nStudent Percentage is = " +per+ "%\n\n");

Example:- Now take an example and check the output step by step. let's take 5 subjects in a semester and we have to calculate percentage out of total number 5 * 100 = 600.

Enter number of subjects: 5
Enter The Marks: 78 65 56 89 90
