Can characters become numeric values?

Question

When strings are mixed with numeric values, they will turn numeric values to characters. I am wondering is it possible for the opposite way to happen: a string literal is turned into numeric values (Ex: the string "123456" turn into the number 123456) ?

Answer 1

Indeed there is! You can convert a String into an int like this:

String numberText = "123456";
int number = Integer.parseInt(numberText);

Or there's another way:

int number = Integer.valueOf(numberText);

Answer 2

If you assign them as variables.
