从扫描仪到BufferedReader的方法转换

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Scanner;

public class ScannerToBufferedReaderExample {
    public static void main(String[] args) {
        // 使用扫描仪读取输入流
        Scanner scanner = new Scanner(System.in);
        System.out.print("请输入一个整数：");
        int num = scanner.nextInt();
        System.out.println("您输入的整数是：" + num);

        // 使用BufferedReader读取输入流
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        try {
            System.out.print("请输入一个整数：");
            int num2 = Integer.parseInt(reader.readLine());
            System.out.println("您输入的整数是：" + num2);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
