Question

I don't really understand how to make the scores show up and how to make it start over. I honestly only half understand the things I've used to piece this together to make this work so far. but this is what I was asked to do.....

1. read a user's first and last name
2. read three integer scores, calculate the total and average
3. 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)
4. Output formatted results consisting of the full name, the three scores, the total, average (to 2 decimal places), and the letter grade
5. go to step 1 if user wants to go through the above 4 steps for another student
6. I am required to use a method for each of the steps 1-4, and required to use a while loop and a nested if in the program in addition to working with methods

and this is what I have so far.......

package speakmanassignment2;

import java.util.*;

public class SpeakmanAssignment2
{
public static void main(String[] args) {
// First & Last Names
String FirstName = getFirstName();
String LastName = getLastName();
Scanner sc = new Scanner(System.in);
int score[]=new int[3];
//Score input
System.out.println("First Score:");
score[0]=sc.nextInt();
System.out.println("Second Score");
score[1]=sc.nextInt();
System.out.println("Third Score");
score[2]=sc.nextInt();
//Total
int total= getTotal(score);
//Average
float average = (float)total/3;
//Calculate grade
char grade = getGrade(average);
//Output
System.out.println("Full name "+FirstName+" "+LastName);
System.out.println("Score 1: %f, Score2:f, Score3:f, ");
System.out.println("Total %.2f"+total);
System.out.printf("Average %.2f ",average);
System.out.println("\n Grade "+grade);

  
}
//Return first name
public static String getFirstName(){
Scanner sc = new Scanner(System.in);
System.out.println("Enter First Name ");
String name = sc.next();
return name;
}
//Return last name
public static String getLastName(){
Scanner sc = new Scanner(System.in);
System.out.println("Enter Last Name ");
String name = sc.next();
return name;
}
//Return scores
{

}
  
//Return total score
public static int getTotal(int a[]){
int total=0;
for(int i=0;i<a.length;i++){
total+=a[i];
}
return total;
}
//Return grade
public static char getGrade(float average){
if(average>=90.00 && average<=100.00)
return 'A';
else if(average>=80.00&&average<=89.99)
return 'B';
else if(average>=70.00&&average<=79.99)
return 'C';
else
return 'F';
}

}

------END------

Any help with this would really be appreciated cause I'm really lost.

Ifyou have any doubts, pelase give me comment

import java.util.*;

public class SpeakmanAssignment2 {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

char choice;

do{

// First & Last Names

String FirstName = getFirstName();

String LastName = getLastName();

int score[] = new int[3];

// Score input

System.out.println("First Score:");

score[0] = sc.nextInt();

System.out.println("Second Score");

score[1] = sc.nextInt();

System.out.println("Third Score");

score[2] = sc.nextInt();

// Total

int total = getTotal(score);

// Average

float average = (float)total / 3;

// Calculate grade

char grade = getGrade(average);

// Output

System.out.println("Full name " + FirstName + " " + LastName);

System.out.printf("Score 1: %d, Score2: %d, Score3: %d\n", score[0], score[1], score[2]);

System.out.printf("Total %d\n",total);

System.out.printf("Average %.2f\n", average);

System.out.println("Grade " + grade);

System.out.print("\nDo you want enter another(Y/N)?");

choice = sc.next().toLowerCase().charAt(0);

}while(choice=='y');

}

// Return first name

public static String getFirstName() {

Scanner sc = new Scanner(System.in);

System.out.println("Enter First Name ");

String name = sc.next();

return name;

}

// Return last name

public static String getLastName() {

Scanner sc = new Scanner(System.in);

System.out.println("Enter Last Name ");

String name = sc.next();

return name;

}

// Return scores

{}

// Return total score

public static int getTotal(int a[]) {

int total = 0;

for (int i = 0; i < a.length; i++) {

total += a[i];

}

return total;

}

// Return grade

public static char getGrade(float average) {

if (average >= 90.00 && average <= 100.00)

return 'A';

else if (average >= 80.00 && average <= 89.99)

return 'B';

else if (average >= 70.00 && average <= 79.99)

return 'C';

else

return 'F';

}
