java控制台(命令行)输入交互(入门级示例)

package com.mingrisoft;import java.io.FileWriter;import java.io.IOException;import java.util.Scanner;public class ConsoleWriter { public static void main(String[] args) { System.out.println("请输入要保存的字符串：");// 提示用户输入字符串 Scanner scanner = new Scanner(System.in);// 获得控制台输入流 String text = scanner.nextLine();// 获得用户输入 FileWriter writer = null; try { writer = new FileWriter("d://test.txt");// 获得文件写入流 writer.write(text);// 写入字符串 writer.flush();// 刷新缓存 } catch (IOException e) { e.printStackTrace(); } finally { if (writer != null) { try { writer.close(); } catch (IOException e) { e.printStackTrace(); } } } }}
