Program:

        int n = in.nextInt();
        
        int rollNo[] = new int[n];

            System.out.println("Enter student " + (i+1) + " details:");
            System.out.print("Roll No: ");
            rollNo[i] = in.nextInt();
            in.nextLine();
            System.out.print("Name: ");

            System.out.print("Subject 3 Marks: ");
            s3[i] = in.nextInt();
            avg[i] = (s1[i] + s2[i] + s3[i]) / 3.0;
        }
        
        System.out.println("Roll No\tName\tRemark");
        for (int i = 0; i < n; i++) {
            String remark;
            if (avg[i] < 40) 
                remark = "Poor";
            else if (avg[i] < 60)
                remark = "Pass";
            else if (avg[i] < 75)
                remark = "First Class";
            else if (avg[i] < 85)
                remark = "Distinction";
            else
                remark = "Excellent";
            System.out.println(rollNo[i] + "\t" 
                + name[i] + "\t"
