例子

下面的示例演示java.io.ObjectInputStream.close()方法的用法。

package com.yiibai;

import java.io.*;

public class ObjectInputStreamDemo {

   public static void main(String[] args) {

      try {

         // create a new file with an ObjectOutputStream
         FileOutputStream out = new FileOutputStream("test.txt");
         ObjectOutputStream oout = new ObjectOutputStream(out);

         // write something in the file
         oout.writeUTF("Hello World");
         oout.flush();

         // create an ObjectInputStream for the file we created before
         ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.txt"));

         // read from the stream
         for (int i = 0; i < ois.available();) {
            System.out.print("" + (char) ois.read());
         }

         // change line
         System.out.println();

         // close the stream
         System.out.println("Closing Stream...");
         ois.close();
         System.out.println("Stream Closed.");

      } catch (Exception ex) {
         ex.printStackTrace();
      }

   }
}

让我们编译和运行上面的程序，这将产生以下结果：

Hello World
Closing Stream...
Stream Closed.
