how to do these program letters with values

[w0ooop]

create a program that will perform the following operation
1. accept 1-5 letters.
2. each letter corresponds to a number.
3. generates the sum of the numbers selected.
4.displays the average of the numbers selected.

values of letter A=20 B=4 C=7 D=9 E=10 F=15 O=6 U=12 S=12
.. joption o scanner only can be use
need it badly asap

What have you done so far? Nobody will do your homework for you. Start yourself and ask specific questions when you get stuck.

[w0ooop]

nope i know..im stuck with how should the operation should be..... im having trouble with question 3 and 4 how should i do the mathematical equation 1 by 1???

[w0ooop]

i use int to specify the equivalent of a letter like int A = 20; or i should use char??

[w0ooop]

should i do that like q = a+ b; q = a + c ?

[w0ooop]

public static void main(String[] args) {
int A = 20,B = 4,C=7,D = 9, E = 10, F = 15, O = 6, U = 12, S = 12;
int q;

Scanner scan = new Scanner(System.in);

System.out.println("Choose 2-5 letter from A,B,C,D,E,F,O,U,S");
q= scan.nextInt();

q = A + B;
q = A + C;
System.out.println("the sum of the enter letter is:"+q);

should i continue this kind of equation??

[PhHein]

scan.nextInt() won't help you here, as the user enters a String. Read the String and make sure it has the correct length and contains only valid characters. If it doesn't match the requirements prompt the user to reenter.
When you're done with that part you can start thinking about converting the input. One after the other, always break down the task into small bits.

[w0ooop]

what should i put q = ?? ishould use loop??

[PhHein]

Forget about ints! Just make sure you can read and verify the user input. Ints come later.

[w0ooop]

how should i do to recognize the letter i type?

[w0ooop]

how should the letter could be recognize?? public static void main(String[] args) {
int A = 20,B = 4,C=7,D = 9, E = 10, F = 15, O = 6, U = 12, S = 12;
int sum,letters=0,q,w;

Scanner scan = new Scanner(System.in);

System.out.println("Choose 2-5 letter from A,B,C,D,E,F,O,U,S");
q = scan.nextInt () ;
System.out.println("Choose 2-5 letter from A,B,C,D,E,F,O,U,S");
w = scan.nextInt () ;
if (letters<2);

sum = q + w;
System.out.println("the sum of the letters is:"+sum);

[PhHein]

Man, keep it simple! You cannot ever read any input from the user as is. One step after the other. Just read any input and print it to the console. After that you can think about validation.

[w0ooop]

i couldnt understand what should ill do to recognize the value of the letter??

[Tolls]

Listen to what PhHein is saying.
You are jumping ahead of yourself.

Software development is about breaking the task in front of you down to the smallest steps.
It is being suggested to you to start with the simple step of reading input from the console into a String variable and output it back to the screen to check it is doing it correctly.

Once you have that code you can then start to look at turning it into numbers.

[w0ooop]

so ishould have string sorry im just new to programming... im not that knowledgeble about it..

[PhHein]

Yes, use a String as input.

[w0ooop]

i dont know how to make it I surrender shit... time to rest hope i had some help how should do it right but thanks to all of you... i hope i can improve on it
