I have "1" as a string, and I would like to convert it to decimal, 1, as integer.
I tried charAt(), but it returns 49, not 1 integer.
So, what is required to convert the "1" string to 1 integer?

You convert a string to a number by calling the Parse or TryParse method found on numeric types ( int , long , double , and so on), or by using methods in the System. Convert class. It's slightly more efficient and straightforward to call a TryParse method (for example, int.
One effective way to convert a string object into a numeral int is to use the stoi() function. This method is commonly used for newer versions of C++, with is being introduced with C++11. It takes as input a string value and returns as output the integer version of it.
Use Wrapper Class.
Examples are below
int
int a = Integer.parseInt("1"); // Outputs 1 float
float a = Float.parseFloat("1"); // Outputs 1.0 double
double a = Double.parseDouble("1"); // Outputs 1.0 long
long a = Long.parseLong("1"); // Outputs 1 If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
