Question

I have text file with string which code page is 1250. I want to save text into RandomAccessFile. When I read bytes from RandomAccessFile I get string with different character. Some solution…

Answer 1

If you’re using writeUTF() then you should read its JavaDoc to learn that it always writes modified UTF-8.

If you want to use another encoding, then you’ll have to “manually” do the encoding and somehow store the length of the byte[] as well.

For example:

RandomAccessFile raf = ...;
String writeThis = ...;
byte[] cp1250Data = writeThis.getBytes("cp1250");
raf.writeInt(cp1250Data.length);
raf.write(cp1250Data);

Reading would work similarly:

RandomAccessFile raf = ...;
int length = raf.readInt();
byte[] cp1250Data = new byte[length];
raf.readFully(cp1250Data);
String string = new String(cp1250Data, "cp1250");
