Write A Program That Translates A Number Between 0 And 4 Into Closest Letter Grade
Oct 8, 2014
Write a program that translates a number between 0 and 4 into the closest letter grade. For example, the number 2.8 (which might have been the average of several grades) would be converted to B. Break ties in favor of the better grade; for example 2.85 should be a B. Use a class Grade with a method getNumericGrade. why when I type .3 it tells me "Exception in thread "main" java.util.InputMismatchException" Or if there is an easier way to do this.
import java.util.Scanner;
public class Grades {
public static void main(String [] args) {
System.out.println("Enter a number between 0 and 4");
Scanner input = new Scanner(System.in);

I am having some trouble with this program. The assignment is to write a program, given a seven-digit phone number, uses a PrintStream object to write to a file every possible seven-letter word combination that corresponds to that number. I have to avoid using 0 or 1. Here is my code.
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.PrintStream;
import java.util.Scanner;
public class TelephoneGenerator
{
String phoneNumber;
char numberLetters[][] = {

Find the numbers which is closest to the average sum for a given array of N (1<=N<=50) of natural numbers. If there are two numbers who meet the requirement, return the smaller of the two.
For example for the array of: 1,2,3,4,5,6 the average sum is 3.5, so both 3 and 4 are the closest to that, but the program has to return 3, because it's smaller than 4.
The array can also contain duplicates. First we type the number of elements in the array, then in each line we add the numbers. Name of the class: Array
**Note**: Create a data structure array and use it.
And this is what they have given to me, I just need to type the code:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class Array<E> {
public static int closestNumber( ) {

The purpose of this project is to determine the letter grade of students. The program needs to accept two command line arguments:
The first being the name of a disk file that contains the names of students, and their test scores, separated by commas followed by one or more spaces. Each line in the file will contain scores for one student.
The second argument is the name of an output disk file. The program is supposed to create a new output disk file using that name.
The number of students in the input file is unknown during compile time. The name of input and output files could be anything and only known during run time. Additionally, the average scores, along with the minimum and maximum scores for each test are to be displayed in the console.
Calculation: Final Score = quiz1 * .10 + quiz2 * .10 + quiz3 * .10 + quiz4 * .10 + midi * .20 + midii * .15 + final * .25
Final Score >= 90% then letter grade is A, 80%-89% B, 70%-79% C, 60-69% D, <= 59% F
input_data.txt:
firstName lastName, 100, 90, 80, 100, 89, 99, 88
firstName lastName, 90, 90, 100, 100, 99, 100, 95
firstName lastName, 100, 90, 100, 70, 78, 78, 80
firstName lastName, 80, 90, 90, 100, 89, 99, 85
etc.
output_data.txt
firstName lastName: B
firstName lastName: A
firstName lastName: F
firstName lastName: B
firstName lastName: C
averages (to appear in console)
Q1 Q2 Q3 Q4 MidI MidII Final
Average: 82.25 80.38 82.85 83.88 81.38 84.13 78.63
Minimum: 60 54 38 62 62 60 50
Maximum: 100 90 100 100 99 100 95

I am trying to create a program that allows me to enter 5 students numeric grade (0-100) to a letter grade (A, B, C, D, F) and I CANNOT use an array. When I try to run my program it says main class not found, and when I change the it from a string to a void in the main method it does not work.
Java Code:
import java.util.Scanner;
public class Week3ControlStatements2
{
public static String main(String[] args){
int numberGrade = 0;
int quotient = numberGrade / 10;
int remainder = numberGrade % 10;

Alright so I wrote a switch statement that decides what range to print based on the letter grade input.
import java.util.Scanner;
public class SwitchPractice
{
public static void main(String [] args)
{
Scanner scan = new Scanner(System.in);
[code]...
It works fine, but once it the user enters a letter grade and then displays the value, it does not prompt the user for another letter grade so that it can perform the output again. Also if I wanted to display an error message to the user if they enter an invalid letter grade how would I do that. I tried using a while loop and if statement in the switch statement but that didn't work.

Ex. If I type 5943, the program will say
mill = 5
hun = 9
ten = 4
uni = 3
get the picture I had to translate the decimal value names from a different language.
This is what I have tried...,
Java Code:
import java.util.Scanner;//Permite el uso de leer el teclado del usuario
public class DeterminarValorDecimal//Nombra el documento
{
public static void main(String [] args)//Podemos ver la clase
{
[Code].....
But what this does is I have to enter the single digits one by one. I want to be able to type the whole number. Is there a method that reads the length of the whole number and lets me classify each digit so I can do what I want to do?

how to I modify my program so that it asks the user how many studens are in the class then according to the value the user inputs that is how many times the program will ask the user for a grade. Once the graded are entered it will then output the class average, minimum, and maximum. I believe that you'd use a for loop yet I am troubled.

I just have not got the chance to spend much time on it lately I know a bit but I'm not an expert or even intermediate with Java so I'm trying to make a program where the teacher enters the grade of each student and its stored in a variable the only problem is if I use a for loop the variable in which the result will be stired will be overwrite by the last repetition of the loop,I think the idea would be a nested loop but how I would go about using it in this situation,
here is my java code.
import java.util.Scanner;
class maths{
public static void main(String[] args)

I'm trying to figure out the correct way to replace number into letter. In this case, I need two steps.
First, convert letter to number. Second, restore number to word.
Words list: a = 1, b = 2, f = 6 and k = 11.
I have word: "baafk"
So, for first step, it must be: "211611"
Number "211611" must be converted to "baafk".
But, I failed at second step.
Code I've tried:
public class str_number {
public static void main(String[] args){
String word = "baafk";
String number = word.replace("a", "1").replace("b","2").replace("f","6").replace("k","11");
System.out.println(word);
[Code] .....
Result for converting to number: baafk = 211611 But, result for converting above number to letter: 211611 = bkfk
What do I miss here?
How to distinguish if 11 is for "aa" and for "k"? D

I had a list of some numbers having a prefix A like A12 , A55, A76 ,A111 ,A888, A88 ,A880 A111 , A11,A1
I need to sort this list so the result would be A1,A11,A12,A55,A76....
How to do this. Can I use arrays.sort method to achieve the same or any other way.

I was trying to write a program that will accept values and transform the scores to grade. Like 70 and above will be given A from 60 to 69 is B, from 50 to 59 is C, from 40 to 49 is D and below 40 is F. I have defined the variables, for the textfield, am confused on how make this hapen on just a click of the comand botton.

I have written a simple grade average program. This is my code:
package programs;
import java.util.Scanner;
public class GradeAverage {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int number;
int counter = 0;
int grade;
[Code] ....
Now the program is working just fine but what I don't like about it is the fact that you have to enter the number of grades before entering the grades. What I would prefer is to write your grades, hit some button that is reserved for calculating the average and then get the output.

So far I've got it where the program is reading the file and returning
a:0
b:0
c:0
d:0
e:0
f:0
g:0
h:0
i:0
j:0
k:0
l:0
m:0
n:0
o:0
p:0
q:0
r:0
s:0
t:0
u:0
v:0
w:0
x:0
y:0
z:0
But I need it to print the letters and then the total amount of each character that is found in the file.

I got a phone number problem. I get a list of phone numbers and a word file containing words, how could I need to see if I could match the phone number to 7 letter words, then see if I can match the first 3 numbers to 3 letter words and then the last 4 numbers to 4 number words. I figured all that out so far. The last part of this assignment is to see if I could match a combination of words together to match the phone numbers.
Example:
531 3259

Many classes calculate a final grade by using a weighted scoring system. For example, "Assignments" might be worth (weighted at) 40% of your final grade. To calculate the portion of the final grade contributed by the Assignments category, the teacher takes the average of all assignments in the category and multiplies it by the weight (40%). So if a student averaged 90% on all assignments, the teacher would take 40% of 90%, or 36 as the weighted average score for the assignment portion of the the final score. The teacher then calculates the weighted average score for each of the other categories (Quizzes, Midterm Exam, Final Exam, etc.), adds them all together to come up with the final score, and assigns a letter grade based on that score.
Write a Java program that allows the teacher to calculate the grade for a student.
Specification :
Prompt the user to enter the Student ID number, first name, last name, and the average score for each of the following categories:
Assignments (worth 50%)
Quizzes (worth 20%)
Midterm Exam (worth 10%)
Final Exam (worth 20%)
Calculate the weighted average score for each category and the total score for the student. Next assign a letter grade as follows:
90 - 100 = A
80 - 89 = B
70 - 79 = C
60 - 69 = D
59 and below = E
Print the results in the following format:
Name: [Last Name], [First Name]
Student ID: [Student ID]
Assignments: [weighted average]
Quizzes: [weighted average]
Midterm Exam: [weighted average]
Final Exam: [weighted average]
Total: [total score]
Final Grade: [letter grade]
Prompt the user to either enter another student or to quit. Continue the process until the user chooses to quit.
I almost done everything but I cant calculate a total score for the student or Assign a letter grade based on the score!!!!
package teacher_grade;
import java.util.Scanner;
public class teachergradeing {
public static void main (String[] args) {
//Scanner objective

I have a problem with functions connected to strings.
I have a random String, e.g. "Hello World!" and I have to change every capital Letter into a small letter and vise versa. This alone would be fairly simple, but I have to do it with two other strings.
lowercase= "abcde...z" and
uppercase="ABCDE...Z". Every small letter stands at the very same position as the capital letter, but in the other string.
There should be a letter for letter search in lowercase and uppercase for the letters of "Hello World".
How I could solve the task, however I need a way to search the first string, here "Hello World", according to position. A statement which does: "Give me the letter of position x". This found letter should be able to be stored in a variable or else be able to be used by another statement. And it should be compatible with a for lope.

Example : I have code and name but my code must start with the first letter of the inputed name if the 2 input is match it will be inserted into database
code = "A"001
name ="Angela"
= success this will inserted into database
else
code ="B"002
name="Angela"
=failed this will not inserted into database
else
code="A"003
name="Andy"
=success still accepts the input cause they have diff code number
What I am thinking on this was compare the code the name? if == it will be inserted but how do i get the 1st letter of the input name?

SO for my project, we have to create a program where we input two four letter words, and using a list of words our teacher provided us and only changing one letter at a time, make the words match.For example, you input BALD and CALL and it would output BALD BALL CALLWe have to use recursion to do this, and I'm totally lost as to where to even begin.

String s1="hi how are you";
s1=s1.replace('a', 'A');
s1 =s1.replace('e', 'E');
s1 =s1.replace('i', 'I');

this is working properly.
but when i trying with Scanner i am facing problem.
