在读取所有字符时是否有理由在InputStreamReader上使用BufferedReader？

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class BufferedReaderExample {
    public static void main(String[] args) {
        try {
            InputStreamReader inputStreamReader = new InputStreamReader(System.in);
            BufferedReader bufferedReader = new BufferedReader(inputStreamReader);

            System.out.println("请输入字符：");
            String input = bufferedReader.readLine();
            System.out.println("您输入的字符是：" + input);

            bufferedReader.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
