How Can I Efficiently Get Single Character Input in Java Using Scanner?

Methods for Taking a Character Input in Java Using Scanner

In Java, if you want to take a character input from the keyboard, there are several approaches you can use.

Firstly, you could use the next().charAt(0) method. This method takes the first character from the Scanner's input buffer. Here's an example:

Scanner reader = new Scanner(System.in);
char c = reader.next().charAt(0);
Copy after login

Secondly, you can use the findInLine(".") method to consume exactly one character from the input buffer. The dot (.) is a placeholder in this case.

char c = reader.findInLine(".").charAt(0);
Copy after login

Lastly, if you want to strictly consume only one character, you can use the next(".") method.

char c = reader.next(".").charAt(0);
Copy after login

These methods provide you with various ways to take character input from the keyboard, depending on your specific requirements. Choose the one that best suits your application's needs.
