java 读bmp文件

Java code

FILE *fp;char sk[50];int col =400;int row =400;unsigned char buf[165000];sprintf(sk,"2.bmp");  fp=fopen(sk,"r+b");  if(fp!=NULL){           fseek(fp,1078,0);     for(int i=0;i<col;i++){         fread(buf+(col-i-1)*row,row,1,fp);     }

vc的代码读bmp文件到buf中，哪位帮忙下用java实现。谢了。

Java code

File file = new File("e:\\abc.bmp");        FileInputStream fis = new FileInputStream("e:\\abc.bmp");                byte[] b = new byte[100];        byte[] fileByte = new byte[(int)file.length()];                int i = -1;        int index = 0;                while((i = fis.read(b, 0, 100)) != -1)        {            for(int j = 0;j < i;j++)            {                fileByte[index++] = b[j];            }        }        fis.close();

public class HelloJava{
  public static void main (String[] args){
  Image image = null;
   try {
       // Read from a file
       File sourceimage = new File("source.gif");  //source.gif图片要与HelloJava.java同在一目录下
       image = ImageIO.read(sourceimage);
  
       // Read from an input stream
       InputStream is = new BufferedInputStream(
          new FileInputStream("mid.jpg"));  //mid.jpg图片要与HelloJava.java同在一目录下
       image = ImageIO.read(is);
  
       // Read from a URL
       URL url = new URL("http://www.javaworld.com/images/012407-tipsbox.jpg");
       image = ImageIO.read(url);
   } catch (IOException e) {
   }
