How I Built a Simple Report Card Program in Java for 15 Subjects Part 2

A few days ago I published an article about making a in Java. I thought I should make this program work if you are having more than 2 subjects, which most of the students have. report card program I forgot to mention, this will also work if you have let’s say 7 subjects, I mean to say this program will accept more than 1 subject and less than or equal to 15. Write a program to take marks of 15 subjects from the user and display the Total, Percentage, Highest Marks, Average, and Remarks. It should also work if the number of subjects is less than 15. Well. looks good. So, starting with formating the old code 😂. Then, I took a variable and asked how many subject are there in total: System.out.println("How many subjects do you have? (Maximum 15, minimum 2)"); int sub_count = sc.nextInt(); A simple condition to make sure the minimum number of subjects should be 2: if (sub_count == 1) { System.out.println("Atleast 2 subjects required"); } Similarly, I made a else condition which will be executed when the number of is more than 15 or less than 2 (also for negative integers, ex- -15, -27): else { System.out.println("Error: Number of subjects should not be more than 15 or not less than 0"); } I added more 14 condition for different inputs, for ex if the number of subjects is 2, this code will be executed: else if (sub_count == 2) { System.out.println("Enter the marks of 2 subjects (out of 100)"); System.out.println("Enter the marks of subject 1:"); int sub1 = sc.nextInt(); System.out.println("Enter the marks of subject 2:"); int sub2 = sc.nextInt(); if (sub1 sub2) { System.out.println("Highest marks scored is " + sub1); } else { System.out.println("Highest marks scored is " + sub2); } // Average float avg = (float) total / 2; System.out.println("Average is " + avg); // Remarks if (percent = 80 && percent = 90) { System.out.println("Remarks: Excellent"); } else { System.out.println("Remarks: Good"); } } else { System.out.println("Values are Greator!"); } } I repeated the same code with some minor changes like, if the no. of subjects is 3 I made one more variable for that and stored the value in it: System.out.println("Enter the marks of subject 3"); int sub3 = sc.nextInt(); I added this variable in this condition so that the value should not be greater than 100: if (sub1 <= 100 && sub2 <= 100 && sub3 <= 100) { // Code } Added the third variable in total: int total = sub1 + sub2 + sub3; System.out.println("Total = " + total + "/300"); Same in Percentage: float percent = (float) total / 300 * 100; System.out.println("Percentage = " + percent + "%"); And for the highest marks first I compared the marks of the first two subjects and added the greater one to another variable then, compared the greater of the two with the marks of the third subject: int max1 = Math.max(sub1, sub2); System.out.println("Highest Marks = " + Math.max(max1, sub3)); Same thing with Average: float avg = (float) total / 3; System.out.println("Average is " + avg); Nothing more is changed, the most important in the highest marks, if the no. of subjects is 4 then this how the code of Highest marks will look: int max1 = Math.max(sub1, sub2); int max2 = Math.max(max1, sub3); System.out.println("Highest Marks = " + Math.max(max2, sub4)); Compared the first 2, stored greater one in a variable, compared the variable with subject 3, stored the greater one in and compared it with the fourth subject.
