ObjectInputStream和ObjectOutputStream

ObjectInputStream和ObjectOutputStream的简单示例

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.Serializable;

public class Main {
	public static void main(String[] args) throws Exception {
		String fileName = "t.tmp"; 
		FileOutputStream fos = new FileOutputStream(fileName); 
		ObjectOutputStream oos = new ObjectOutputStream(fos);
		oos.writeObject(new Point(1, 1)); 
		oos.writeObject(new Point(2, 2));
		fos.close(); 
		oos.close(); 
		
		FileInputStream fis = new FileInputStream(fileName); 
		ObjectInputStream ois = new ObjectInputStream(fis);
		while(true){
			Point tp = null; 
			try {
				tp = (Point)ois.readObject();
			} catch (Exception e) {
				break;
			}
			System.out.println(tp.getx() + "  " + tp.gety());
		}
		System.out.println("over");
		fis.close();
		ois.close(); 
	}
}
class Point implements Serializable{
	private static final long serialVersionUID = 1127043316960106769L;
	private int x, y; 
	Point(int x, int y){
		this.x = x; 
		this.y = y; 
	}
	
	public int getx(){
		return x; 
	}	
	public int gety(){
		return y; 
	}
}
