void flush int skipBytes(int n) int size 描述 所述java.io.DataOutputStream.flush()方法力字节被写入到基础流。 声明 以下是java.io.DataOutputStream.flush()方法的声明 public void flush() 参数 NA 返回值 此方法不返回任何值。 异常 IOException - 如果发生I / O错误。 实例 以下示例显示了java.io.DataOutputStream.flush()方法的用法。 package com.tutorialspoint; import java.io.DataInputStream; import java.io.DataOutputStream; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; public class DataInputStreamDemo { public static void main(String[] args) throws IOException { InputStream is = null; DataInputStream dis = null; FileOutputStream fos = null; DataOutputStream dos = null; String[] s = {"Hello", "World!!"}; try { // create file output stream fos = new FileOutputStream("c:\\test.txt"); // create data output stream dos = new DataOutputStream(fos); // for each string in string buffer for(String j:s) { // write string encoded as modified UTF-8 dos.writeUTF(j); } // forces data to the underlying file output stream dos.flush(); // create file input stream is = new FileInputStream("c:\\test.txt"); // create new data input stream dis = new DataInputStream(is); // available stream to be read while(dis.available()>0) { // reads characters encoded with modified UTF-8 String k = dis.readUTF(); // print System.out.print(k+" "); } } catch(Exception e) { // if any error occurs e.printStackTrace(); } finally { // releases all system resources from the streams if(is!=null) is.close(); if(dis!=null) dis.close(); if(fos!=null) fos.close(); if(dos!=null) dos.close(); } } } 让我们编译并运行上面的程序,这将产生以下结果 Hello World!! int skipBytes(int n) int size
