java读取钱龙股票软件下载的日线数据核心代码

最近对网上同仁们的代码进行了研究,写出了此代码,大家共同学与进步,也感谢在网上发布优秀代码的同仁们

钱龙中日线数据存储在QLDATA\history\shase\day和QLDATA\history\sznse\day目录下，每个文件对应一只股票。

首先定义一个对象如下

package lgj.qldata;

public class gpStruct {

int nDate=0;
int nOpenPrice =0;
int nHighestPrice=0;
int nLowestPrice=0;
int nClosePrice=0;
int nAmount=0;

int nTransCount=0;
int nPadding1=0;
int nPadding2=0;
int nPadding3=0;
public int getNAmount() {
  return nAmount;
}
public void setNAmount(int amount) {
  nAmount = amount;
}
public int getNClosePrice() {
  return nClosePrice;
}
public void setNClosePrice(int closePrice) {
  nClosePrice = closePrice;
}
public int getNDate() {
  return nDate;
}
public void setNDate(int date) {
  nDate = date;
}
public int getNHighestPrice() {
  return nHighestPrice;
}
public void setNHighestPrice(int highestPrice) {
  nHighestPrice = highestPrice;
}
public int getNLowestPrice() {
  return nLowestPrice;
}
public void setNLowestPrice(int lowestPrice) {
  nLowestPrice = lowestPrice;
}
public int getNOpenPrice() {
  return nOpenPrice;
}
public void setNOpenPrice(int openPrice) {
  nOpenPrice = openPrice;
}
public int getNPadding1() {
  return nPadding1;
}
public void setNPadding1(int padding1) {
  nPadding1 = padding1;
}
public int getNPadding2() {
  return nPadding2;
}
public void setNPadding2(int padding2) {
  nPadding2 = padding2;
}
public int getNPadding3() {
  return nPadding3;
}
public void setNPadding3(int padding3) {
  nPadding3 = padding3;
}
public int getNTransCount() {
  return nTransCount;
}
public void setNTransCount(int transCount) {
  nTransCount = transCount;
}

}

读取的方法代码如下

public void insertqldata(){

// TODO Auto-generated method stub
  FileInputStream fin=null;
  DataInputStream in=null;
  try{
   File f=new File("c:\\000498.day");

   //long fileength=f.length();
   byte[] buf=new byte[40];

  //DataInputStream in = new DataInputStream(new FileInputStream("c:\\000498.day"));

  int i=32;


   fin = new FileInputStream(f);
   in = new DataInputStream(fin);
  int num=0;

  long totalsize=0;
  long filelength=f.length();

  ArrayList list=new ArrayList();

  while(totalsize<filelength){

   gpStruct gps=new gpStruct();

   totalsize+=40;

   if(totalsize>filelength){
    byte[]leftpart=new byte[40-(int)(totalsize-filelength)];
    in.readFully(leftpart);

    gps.nDate=(leftpart[0]&0xFF) |((leftpart[1]&0xFF)<<8) |((leftpart[2]&0xFF)<<16)|((leftpart[3]&0xFF)<<24);
    System.out.println("---gps.nDate--"+gps.nDate);

    list.add(gps);
   }else{

    list.add(gps);
   }
  }

in.close();
