将日期对象和向量对象写入文件,然后从文件中读出并输出到屏幕上 ```java package objstream; import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.FileOutputStream; import java.io.IOException; import java.io.ObjectInputStream; import java.io.ObjectOutputStream; import java.util.Date; import java.util.Vector; import java.util.logging.Level; import java.util.logging.Logger; import javafx.scene.chart.PieChart.Data; /** * * @author Administrator */ public class ObjStream { /** * @param args the command line arguments */ public static void main(String[] args) throws IOException { try { //这2句与FileOutputStream fout = new FileOutputStream("test.txt"); //是等价的 FileOutputStream fout = null; File f = new File("test.txt"); Vector v = new Vector(); //Vector变量 v.add("不求有功"); v.add("才华出众"); v.add("瞬息万变"); fout = new FileOutputStream(f); ObjectOutputStream Obj = new ObjectOutputStream(fout); Object Oj = new Object(); Oj = new Date(); Obj.writeObject(Oj); Obj.writeObject(v); Obj.close(); FileInputStream Fin = new FileInputStream(f); ObjectInputStream Ois = new ObjectInputStream(Fin); Object Oji = new Object(); //这里为什么要用2个OBJECT来输出求指教 Oji = Ois.readObject(); //不用2个的话只输出时间 System.out.println(Oji); Object Oji2 = new Object(); Oji2 = Ois.readObject(); System.out.println(Oji2); } catch (FileNotFoundException ex) { Logger.getLogger(ObjStream.class.getName()).log(Level.SEVERE, null, ex); } catch (ClassNotFoundException ex) { Logger.getLogger(ObjStream.class.getName()).log(Level.SEVERE, null, ex); } } } ``` 对象输入流)可读取使用对象输出流写入的原始数据和类型,与文件输入输出流一起可以实现对象的持久性存储。结果: Fri Jul 24 11:28:01 CST 2015 [不求有功, 才华出众, 瞬息万变] 成功构建 (总时间: 2 秒)但是test.txt文件里是乱码~~怎么破??总结原文地址: http://blog.csdn.net/sac761/article/details/47038609
