Answer:
letter?
As for other spacing, it's traditional to double space between the date and the salutation, double space after the salutation, and triple space for the signature. However, it's fine to only double space after the date, especially if doing so will save the letter from running on to a second page.

See Explaination 
Explanation:
package testscores;
import java.util.ArrayList;
import java.util.List;
public class TestScores {
 
public List<Integer> scorearray=new ArrayList<>();
public TestScores(List<Integer> scores) throws InvalidTestScore{
this.scorearray=scores;
for(int i=0;i<scorearray.size();i++){
if(scorearray.get(i)>100 || scorearray.get(i)<0){
throw new InvalidTestScore(this.scorearray.get(i));
}
}
 
}
public double average(){
int tot=0;
for(int i=0;i<this.scorearray.size();i++){
tot=tot+this.scorearray.get(i);
}
return tot*(1.0)/(this.scorearray.size());
}
class InvalidTestScore extends Exception
{
private double amount;
public InvalidTestScore(int Score)
{
System.out.println("Invalid Score "+Score);
}
 
}
}

The code segment makes use of conditional statements.
Conditional statements in programming are used to make decisions
The code segment in C++ is as follows
if (score > 90) {
grade = 'A';
}
else if (score >= 80 && score < =90) {
grade = 'B';
}
else {
grade = 'C';
}
The above code segments take the score, make comparison, and then determine the appropriate letter grade.
