java datainputstream和dataoutputstream详解

操作基本数据类型的流 

datainputstream

dataoutputstream

import java.io.datainputstream;
import java.io.dataoutputstream;
import java.io.fileinputstream;
import java.io.fileoutputstream;
import java.io.ioexception;
 
public class integerdemo {
  public static void main(string[] args) throws ioexception {
    mywrite();
 
    myreader();
  }
 
  private static void mywrite() throws ioexception {
    // todo auto-generated method stub
    // 创建数据输出流对象
    fileoutputstream fos = new fileoutputstream("e:\\zikao\\file\\cs.txt");
    dataoutputstream dos = new dataoutputstream(fos);
 
    // 写数据
    dos.writebyte(10);
    dos.writeshort(100);
    dos.writeint(1000);
    dos.writelong(10000);
    dos.writefloat(12.34f);
    dos.writedouble(12.56);
    dos.writechar('a');
    dos.writeboolean(true);
 
    // 释放资源
    dos.close();
  }
 
  private static void myreader() throws ioexception {
    // todo auto-generated method stub
    // 创建数据输入流对象
    fileinputstream fis = new fileinputstream("e:\\zikao\\file\\cs.txt");
    datainputstream dis = new datainputstream(fis);
 
    // 读数据
    byte b = dis.readbyte();
    short s = dis.readshort();
    int i = dis.readint();
    long l = dis.readlong();
    float f = dis.readfloat();
    double d = dis.readdouble();
    char c = dis.readchar();
    boolean bl = dis.readboolean();
 
    // 释放资源
    dis.close();
 
    system.out.println(b);
    system.out.println(s);
    system.out.println(i);
    system.out.println(l);
    system.out.println(f);
    system.out.println(d);
    system.out.println(c);
    system.out.println(bl);
  }
}
