![]() ![]() Even if the character variable has a numerical value, its ASCII will be displayed in this method, one way to convert char into int java, when char value is numerical is to subtract 48 from them.Īnother way is the Character.getValue(). The first way of conversion of char to int java the char variable is assigned to an integer variable, this method returns the ASCII value of the character variable. This code is to practice all the methods discussed above, dry run the code, and run it afterward import java.util.* ("the value of integer variable 4 would be : " + Integer.parseInt(String.valueOf(character_variable4))) ĪLSO READ: String Interpolation in Java Explained Practice Code ("the value of integer variable 3 would be : " + Integer.parseInt(String.valueOf(character_variable3))) ("the value of integer variable 2 would be : " + Integer.parseInt(String.valueOf(character_variable2))) ("the value of integer variable 1 would be : " + Integer.parseInt(String.valueOf(character_variable1))) use the parseInt and valueOf method for char to int java conversion So to use this method for the char to int java conversion, we first convert the character variable into a string, using the String.valueOf() method, then we convert it into an integer using Integer.ParseInt(String) method. The Integer.ParseInt() method takes a string as a parameter and returns an integer value of the parameter provided, while the String.valueOf method is used to convert any datatype i.e. Method-3 : Integer.ParseInt(String) using String.valueOf() method Int integer_variable4 = Character.getNumericValue(character_variable4) Int integer_variable3 = Character.getNumericValue(character_variable3) Int integer_variable2 = Character.getNumericValue(character_variable2) Int integer_variable1 = Character.getNumericValue(character_variable1) ![]() use the method Character.getNumericValue() for char to int java conversion The example is shown in the code below : import java.util.* This method is of the character class and it returns an integer value of the number assigned to a character variable. The output of this code is the value of integer variable 1 would be : 1īut since this method is ineffective we use character.getNumericalValue() method.ĪLSO READ: How to convert String to Date in Java ("the value of integer variable 1 would be : " + integer_variable1) Int integer_variable4 = character_variable4 - '0' Int integer_variable3 = character_variable3 - '0' ![]() Int integer_variable2 = character_variable2 - '0' Int integer_variable1 = character_variable1 - '0' The same can be done by subtracting char ‘0’ from the character asci value, the code below demonstrates how: The value of integer variable 4 would be : 4 The value of integer variable 3 would be : 3 The value of integer variable 2 would be : 2 The output of the following code will be the value of integer variable 1 would be : 1 ("the value of integer variable 4 would be : " + integer_variable4) ("the value of integer variable 3 would be : " + integer_variable3) ("the value of integer variable 2 would be : " + integer_variable2) ![]() ("the value of integer variable 1 would be: " + integer_variable1) Int integer_variable4 = character_variable4 - 48 Int integer_variable3 = character_variable3 - 48 Int integer_variable2 = character_variable2 - 48 Int integer_variable1 = character_variable1 - 48 Like in the code below: import java.util.* The value of integer variable 4 would be the ASCII of D i.e : 68ĪLSO READ: How to get Current Date in Java Įven if the character variable has a numerical value, its ASCII will be displayed in this method, one way to convert char into int java, when char value is numerical is to subtract 48 from them. The value of integer variable 3 would be the ASCII of C i.e : 67 The value of integer variable 2 would be the ASCII of B i.e : 66 The output of this code is the value of integer variable 1 would be the ASCII of A i.e : 65 ("the value of integer variable 4 would be the ASCII of " + character_variable4 + " i.e : " + integer_variable4) ("the value of integer variable 3 would be the ASCII of " + character_variable3 + " i.e : " + integer_variable3) ("the value of integer variable 2 would be the ASCII of " + character_variable2 + " i.e : " + integer_variable2) ("the value of integer variable 1 would be the ASCII of " + character_variable1 + " i.e : " + integer_variable1) Int integer_variable4 = character_variable4 Int integer_variable3 = character_variable3 Int integer_variable2 = character_variable2 Int integer_variable1 = character_variable1 A demonstration is shown in the code below: import java.util.* These methods are explained in the article ![]()
