Opening the comment @ cy6erGn0m , you read the character from the console, but save it not as a character, but as the code of that character, for example, as ASCII code. And accordingly, it will be displayed by the function System.out.print(int i); instead of System.out.print(char c);

To avoid this, either save the character in some way, like a character, or output using, for example, a type conversion.
