If we direct assign char variable to int, it will return ASCII value of given character. Returns a Character instance representing the specified char value. There are various ways in which one can convert char to its int value. But if we are working with arbitrarily more numbers of data of same type, array can be a good choice because it is a simple data structure to work with. Casting is also required when we want to convert ASCII value into character. It can only convert char to int in java when there are numeric values stored in the char data type.
