以下示例显示java.io.ObjectOutputStream.drain()方法的用法。
package com.jc2182;
import java.io.*;
public class ObjectOutputStreamDemo extends ObjectOutputStream{
public ObjectOutputStreamDemo(OutputStream out) throws IOException {
super(out);
}
public static void main(String[] args) {
int i = 319874;
try {
// create a new file with an ObjectOutputStream
FileOutputStream out = new FileOutputStream("test.txt");
ObjectOutputStreamDemo oout = new ObjectOutputStreamDemo(out);
// write something in the file
oout.writeInt(i);
oout.writeInt(1653984);
// drain the stream
oout.drain();
// close the stream
oout.close();
// create an ObjectInputStream for the file we created before
ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.txt"));
// read and print an int
System.out.println("" + ois.readInt());
// read and print an int
System.out.println("" + ois.readInt());
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
