I am getting an ASCII value and I want to convert it into an integer because I know it's an Integer ASCII value.
int a=53;
This is an ASCII value for 5. How would I be able to convert it to an integer?

Very simple. Just cast your char as an int . char character = 'a'; int ascii = (int) character; In your case, you need to get the specific Character from the String first and then cast it.
To convert the ASCII value back to int , we can use the ord() function. The ord() has the general purpose of acquiring a string of unit length and providing the Unicode equivalence of the string passed as an argument.
In C programming, a character variable holds ASCII value (an integer number between 0 and 127) rather than that character itself. This integer value is the ASCII code of the character. For example, the ASCII value of 'A' is 65.
We can convert char to int by negating '0' (zero) character. char datatype is represented as ascii values in c programming. Ascii values are integer values if we negate the '0' character then we get the ascii of that integer digit.
int asciiValue = 53;
int numericValue = Character.getNumericValue(asciiValue);
System.out.println(numericValue);
int yourInt = Integer.parseInt(yourString);
