please help !need rush. i dont know how the computations should be done.. :(

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
either or joption o scanner ang gagamitin

just a newbie with Data structure and algo please help to solve this .. ...

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?? or how should the computation should be done

can i ask how can a letter with value can be recognize in a program??

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



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);


if (letters<2);
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 () ;
sum = q + w;
System.out.println("the sum of the letters is:"+sum);

Code :

---

int A = 20,B = 4,C=7,D = 9, E = 10, F = 15, O = 6, U = 12, S = 12;

The names of variables are not useful when looking that user input.
There are several ways to associate a letter input by a user with a value:
One is to use a switch statement
Another is to use a String and an array of the values with the letter's position in the String corresponding to the index into the array.
Another would be a Map with the letter being the key and the value being the numeric value.

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);




the value of the letter couldn't recognize

Please explain the problem.

The code uses the wrong Scanner method to read a letter. nextInt() is for reading numbers.
