I am new to writing in Java. I've been slacking probably more than I should be, and I have a small project that is due on Thursday for my class. Currently, I know how to write in C++ and C++ only. If someone could help me in writing the simple code for my project, that would be great.

The program is simple. It should allow a user to input a string of digits, and then output the sum of those digits.

For example; the user inputs 3563
the program would then output 17 (3+5+6+3)

Thanks for any help.

well .... the program starts with:

(Toggle Plain Text)

class name{
     public static void main (String args[]){
         int n=Integer.parseInt(args[0]);
          int S=0; // it's the sum of digits  ..... 
    // u declare some other variables ... the same way .. if you need .... 

          //u do your thing, if u know in c++ .. it's the same in java

          System.out.println(S);// print the sum
}
}

that shouwld be about all ..... show us the code if u can't crack it

.. good luck

also, the name of the file has to be exactly the same as the name of the class
