怎样将一个文本文件转换成十六进制形式

怎样将一个文本文件转换成十六进制形式

I hope the code below is what you want.
Could you just describe your requirement much detail, like :
we have a data file, which is binary:
58 00 00 00 B8 1F 00 00 F1 54 C8 2A 1B DF F3 AA
I want it to be:
.......

In fact the 16 radix data you see is just a way for representation, you might want to see the result with 10 radix, but the value is still kept the same, correct?

BufferedInputStream in = null;
BufferedOutputStream out = null;
try {
in = new BufferedInputStream(new FileInputStream(FILENAME));
out = new BufferedOutputStream(new FileOutputStream(FILEOUT));
byte[] buff = new byte[60];
int cnt = in.read(buff, 0, 60);
for (int i =0; i < cnt; ++i) {
String val = Byte.toString(buff[i]);
out.write(Byte.valueOf(val, 10));
}
} finally {
if (null != in)
in.close();
if (null != out)
out.close();
}
