How to enter a character in java

Idea:

First create a Scanner object, call the next() method of the Scanner object to obtain the string input by the console, and return It is a String type. Since there is no nextChar() method, the charAt(0) method of String is called to get the first character. In this way, we input a string.

Method to enter a character:

import java.util.Scanner;
Scanner scanner = new Scanner(System.in);
char c = scanner.next().charAt(0);	

This is by far the most commonly used method, which is the black letter principle above.

import java.util.Scanner;
Scanner scanner = new Scanner(System.in);
char c = scanner.next().toCharArray()[0];

This one is so-so to use, not as easy to use as the first one, a waste of resources, and not as simple as the first one.

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
char c = (char)new BufferedReader(new InputStreamReader(System.in)).read();
