Input: ch = "3"Output: 3Input: ch = "9"Output: 9Integer: The integer or int data type is a 32-bit signed two’s match integer. The value-range lies between – 2,147,483,648 (-2^31) come 2,147,483,647 (2^31 -1) (inclusive). That is minimum value is – 2,147,483,648 and maximum worth is 2,147,483,647. That is default value is 0. The int data kind is generally used together a default data kind for integral values unless there is no trouble with memory.Example: int a = 10Character: The char data kind is a solitary 16-bit Unicode character. That is value-range lies in between ‘u0000’ (or 0) to ‘uffff’ (or 65,535 inclusive).The char data kind is provided to save characters.
Example: char ch = "c"
ApproachesThere are countless approaches to perform the switch of Char datatype come Integer (int) datatype. A couple of of lock are provided below.Using ASCII ValuesUsing String.valueOf() MethodUsing Character.getNumericValue() Method
1. Making use of ASCII valuesThis technique uses TypeCasting to obtain the ASCII worth of the offered character. The corresponding integer is calculated native this ASCII worth by individually it indigenous the ASCII value of 0. In various other words, this technique converts the char to int by detect the difference between the ASCII value of this char and the ASCII value of 0.Example:
2. Utilizing String.valueOf() methodThe method valueOf() of course String can convert various types of values to a wire value. It can transform int, char, long, boolean, float, double, object, and char selection to String, which deserve to be convert to an int worth by using the Integer.parseInt() method. The below program illustrates the usage of the valueOf() method.

3. Making use of Character.getNumericValue() methodThe getNumericValue() an approach of class Character is supplied to acquire the integer value of any particular character. Because that example, the personality ‘9’ will certainly return an int having actually a worth of 9. The listed below program illustrates the use of getNumericValue() method.Example:
