void writeShort(int v) void writeLong(long v) void writeUTF(String str) 描述 所述java.io.DataOuputStream.writeShort(int v)按方法短值写入到基础流为两个字节。成功调用此方法后,写入的计数器将增加2。 声明 以下是java.io.DataOutputStream.writeShort(int v)方法的声明 public final void writeShort(int v) 参数 v - 要写入输出流的short。 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.writeShort(int v)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 DataOutputStreamDemo { public static void main(String[] args) throws IOException { InputStream is = null; DataInputStream dis = null; FileOutputStream fos = null; DataOutputStream dos = null; short[] s = {12982,3568}; try { // create file output stream fos = new FileOutputStream("c:\\test.txt"); // create data output stream dos = new DataOutputStream(fos); // for each short in short buffer for(short j:s) { // write short to data output stream dos.writeShort(j); } // force 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) { // read two bytes from data input, return short short k = dis.readShort(); // print short value 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 12982 3568 void writeLong(long v) void writeUTF(String str)
