Similarly, we get ASCII values for numeric values and special character as well as follows:ĪSCII value of –>64 #2) Using Character.getNumericValue() Method The difference in values for ‘P’ and ‘p’ is because ASCII values are different for upper case letters and small case letters. In the above program, we can see the ASCII values of different char variable values as follows: Assign character char2 to int variable int4 Assign character char3 to int variable int3 Assign character char2 to int variable int2 Assign character to char variable char4Ĭhar char4 = Assign character char1 to int variable int1 Assign character '2' to char variable char3 Assign character 'p' to char variable char2 Assign character 'P' to char variable char1 * This class demonstrates sample code to convert char to int Java program In the following sample Java program, let’s see how to convert character to int through implicit typecast i.e. This is because when we assign char variable value ‘a’ to int variable ‘b’, we actually retrieve the ASCII value of ‘1’ which is ‘49’. If we print the value of ‘b’, then you will see console prints ‘49’. Here char ‘a’ gets implicitly typecast to the int data type. when we assign the following char variable value to the variable ‘int’ data type, then the char variable value gets converted to an int automatically by the compiler. Implicit type casting happens for the ‘char’ data type variable as well i.e. implicitly gets typecast to a variable of the larger data type.įor Example, if we assign a variable of type int to a variable of type long, then the int value automatically gets typecast to data type long. In Java, if you assign a smaller data type value to a variable of the compatible larger data type variable, then the value gets automatically promoted i.e. Let us have look at these methods in detail. Java provides various methods to convert character to an int value. In such cases, these values need to be first converted to int data type to perform numeric operations on these values further. int values, and then perform the desired actions, calculations on these.įor example, in some software systems, certain operations need to be performed, or some decisions must be taken based on the customer ratings received in the customer feedback form which comes as the character data type. In such cases, we have to first convert these character values to numeric values i.e. In some scenarios, it is required to perform operations on numeric values, where variable values are specified in the data type of char. Java has primitive data types like int, char, long, float, etc. #4) Convert Char To int In Java By Subtracting ‘0’.#3) Using Integer.parseInt() And String.ValueOf() Method.#2) Using Character.getNumericValue() Method.
