Question

Modify the Assignment program from Module 1 to read a user's first and last name read three integer scores, calculate the total and average determine the letter grade based on the following criteria - Average 90-100 grade is A, 80-89.99 grade is B, 70-79.99 grade is C, all others F (use a nested if) Output formatted results consisting of the full name, the three scores, the total, average (to 2 decimal places), and the letter grade go to step 1 if user wants to go through the above 4 steps for another student You are required to use a method for each of the steps 1-4 . This program DOES NOT involve creating a class as covered in chapter 3.

Hint: you are required to use a while loop and a nested if in this program in addition to working with methods. Method main will mainly have declarations and calls to these methods. You may call a method multiple times Include a pledge that the programs were entirely your work and specify the IDE used to write these programs

write a headerMethod to output the descriptive header
Write one nameMethod and call it twice (value returning)
write one scoresMethod and call it three times
a value returning method to retun the total
a value returning method to return the average
a value returning method to return the letterGrade
an outputMethod to output formatted results (first and last name, the 3 scores,
total average, and letter grade

Please you use java code. And it keep simple, because its an intro crouses

Answer 1

Code

import java.util.Scanner;

public class Student {
static Scanner scnr=new Scanner(System.in);
public static void main(String[] args) {
String first_name,last_name;
int score1,score2,score3,total;
double avg;
char again='y',letterGrade;
  
while(again=='y')
{
first_name=nameMethod ("Enter first name: ");
last_name=nameMethod ("Enter last name: ");
score1=scoresMethod(1);
score2=scoresMethod(2);
score3=scoresMethod(3);
total=getTotal(score1,score2,score3);
avg=getAverage(total);
letterGrade=getLatterGrade(avg);
outputMethod(first_name,last_name,score1,score2,score3,avg,letterGrade);
System.out.print("\nDo you want to do for another student? (y/n): ");
again=scnr.next().charAt(0);
System.out.println();
}
  
}

private static String nameMethod(String msg) {
System.out.print(msg);
return scnr.next();
}

private static int scoresMethod(int i) {
System.out.print("Enter score "+i+": ");
return scnr.nextInt();
}

private static int getTotal(int score1, int score2, int score3) {
return score1+score2+score3;
}

private static double getAverage(int total) {
return total/3.0;
}

private static char getLatterGrade(double avg) {
if(avg>=90.00)
return 'A';
else if(avg>=80.00)
return 'B';
else if(avg>=70.00)
return 'C';
else if(avg>=60.00)
return 'D';
return 'D';
}

private static void outputMethod(String first_name, String last_name, int score1, int score2, int score3, double avg, char letterGrade) {
String fullname=first_name+" "+last_name;
String format = "%1$-15s%2$-10d%3$-10d%4$-10d%5$-10.2f%6$-10s\n";
String format1 = "\n%1$-15s%2$-10s%3$-10s%4$-10s%5$-10s%6$-10s\n";
System.out.format(format1,"Name","Score1","Score2","Score3","Average","Letter Grade");
System.out.format(format,fullname,score1,score2,score3,avg,letterGrade+"");
}
  
  
}

output
