As @user15793316 already said, System.in.read() does not read the actual number. You can make use of Scanner instead:

Edit: The user has stated they would like one method to be used for two different text boxes/buttons. I have updated the code to reflect this. What now happens is the function that is added as an onclick handler is passed a element as a parameter. This is the element the same function should change and perform and action to.

Here you go.

The thing you need to do is select multiple elements by separating them with a , character. @john-slegers does an amazing job of explaining jQuery selectors here..

EDIT: BETTER WAY

INSTEAD OF EDITING THE STRING IN THE SERVER WE SHOULD ENCODE IN ANDROID THIS WAY

Base64.encodeToString(bytes, Base64.NO_WRAP);

AND GET IT IN THE SERVER THE USUAL WAY WITHOUT EDITING THE STRING

java.util.Base64.getMimeDecoder().decode(yourByteArray);

PREVIOUS WAY:

I just had to edit the String that i was getting in the server by removing the quotes surrounding it with img.substring(1, img.length() - 1) and the \n with img.replace("\\n", "").

The result code in the server is like this:

Given:

Let RDKit compute 2D coordinates and use the CoordGen library.

The second argument of scanf needs to be a pointer (memory adress) to an integer...

So, replace the line:

It is a concise form of testing two conditions and assigning the logical result.

If using bash, one approach is to store the bad numbers as keys in an associative array and see if that particular key exists when validating a number:

In your menu() function,

Instead of immediately casting the input into an int, you can use a try statement to make sure the input is an integer, so if the user types in a letter your program will not stop. For example:
