File Name: GradeCalculation.java
Program Description: Determine someone's grade.
*/
import java.util.*;

public class GradeCalculation {
public static void main( String[] args ){

// Variable to accept the user's input
Scanner keyboard = new Scanner(System.in);

// Enter your code here
    // Taking input
    float test,lab,hw,quiz;
    System.out.print("Input test%: ");
    test=keyboard.nextFloat();
    System.out.print("Input lab%: ");
    lab=keyboard.nextFloat();
    System.out.print("Input HW%: ");
    hw=keyboard.nextFloat();
    System.out.print("Input quiz%: ");
    quiz=keyboard.nextFloat();
  
    // Calculating final grades
    double grade=(test/2)+(3*lab/10)+(hw/10)+(quiz/10);
    String s;
  
    // Checking which grade student is getting.
    if(grade>=92.5)
        s="A";
    else if(grade>=89.5 && grade<92.5)
        s="A-";
    else if(grade>=86.5 && grade<89.5)
        s="B+";
    else if(grade>=82.5 && grade<86.5)
        s="B";
    else if(grade>=79.5 && grade<82.5)
        s="B-";
    else if(grade>=76.5 && grade<79.5)
        s="C+";
    else if(grade>=72.5 && grade<76.5)
        s="C";
    else if(grade>=69.5 && grade<72.5)
        s="C-";
    else if(grade>=66.5 && grade<69.5)
        s="D+";
    else if(grade>=62.5 && grade<69.5)
        s="D";
    else if(grade>=59.5 && grade<62.5)
        s="D-";
    else
        s="F";
  
    // Printing the output.
    System.out.println("Your final percentage is "+grade+"%,meaning you have a "+s+".");
}
