Q - Write a java program to calculate the letter grades of each student in the class based on the scale shown on the course overview and the syllabus. Which type of decision structure would be best for this and why? and which statement would you use? If, if-then, if-then-else, switch, others?
A - Figure out how to use the switch statement because it evaluates the variable and jumps directly to the case for that value, but in this example you have a range of values (i.e. 90-100) for an A, you can't use the switch statement you have to use the if-then-else statement.
Example Calculating letter grades
import java.util.Scanner;
public class template
{
public static void main (String[] args)
{
Scanner keyboard = new Scanner (System.in);
double grade; //assign value to grade variable
System.out.print ("Enter grade in number value 1-100 ");
grade = keyboard.nextDouble();
if (grade >=90)
System.out.println ("A");
else if (grade >=80)
System.out.println ("B");
else if (grade >=70)
System.out.println ("C");
else if (grade >=60)
System.out.println ("D");
else if (grade <60)
System.out.println ("F");
} // end main
} // end class template
