关于文件结束符~~~~

[isaxu]

要对一个文件流进行读操作，
RandomAccessFile fin = new RandomAccessFile("matchTable.dat","r");
怎样判断是否已经读到文件结尾了呢？
while(fin.read() !='EOF')
这个文件结束符编译通不过阿~~~~
请各位大虾指教拉~
3Q!^_^

[nicklegao]

byte[] bBytes = new byte[102400];
FileInputStream infile = new FileInputStream(a);
FileOutputStream outfile = new FileOutputStream(b);
int nRead ;
while ((nRead = infile.read(bBytes, 0, 102400)) > 0) {
outfile.write(bBytes,0,nRead);
}
infile.close();
outfile.close();

RandomAccessFile fin = new RandomAccessFile("matchTable.dat","r");
long filePoint = 0;//文件指针
long fileLength = fin.length();//获得文件的长度
while(filePoint < fileLength) {//指针小于文件的长度，则不到文件结尾
System.out.println(fin.readLine());
filePoint = fin.getFilePointer();//读过文件内容后得到当前指针的位置
}

int bytes_read;
byte[] buffer = new byte[4096]; // To hold file contents
while((bytes_read = fin.read(buffer)) != -1)

断是否已经读到文件结尾了
