Hi,
I have the following code:
//-----
1 public static String leer(BufferedReader sin) {
2 StringBuffer line = new StringBuffer();
3
4 try {
5
6 for (int ch; (ch = sin.read()) != 1; ){
7 line.append(ch);
8 }
9
10 } catch (IOException e) {
11 System.out.println("leer: " + e.toString());
12 }
13 if (linea != null)
14 System.out.println(line.substring(0));
15 return line.substring(0);
16 }
//-----
The problem is, at line 6, "sin.read()" returns a int (which is a unicode code) and I need the equivalent character to build a string. How can I obtain the character that corresponds to this unicode code?
Thanks in advance.

You may cast the type to char. The loop condition does need some int, I guess if you do the casting in the loop condition, there would be some problem....hmmm, but where should you cast it? Maybe try here: line.append((char)ch); But I am not sure of this....
BTW, try to use the UBB tab "CODE", it would make others much easier to read your code
