In alpha3 try java.io.TextInputStream.readLine();
in beta try java.io.DataInputStream.readLine();
Canonical example:
class CopyFile {
public static void main(String args[]) {
FileInputStream in = null;
FileOutputStream out = null;
try {
in = new FileInputStream(args[0]);
out = new FileOutputStream(args[1]);
} catch (Throwable e) {
System.out.println("Usage: java CopyFile file1 file2");
System.exit(1);
}
// fgets equivalent
DataInputStream dis = new DataInputStream(in);
// fputs equivalent
PrintStream ps = new PrintStream(out);
String tmp;
while ((tmp = dis.readLine()) != null)
ps.println(tmp);
in.close();
out.close();
}
}
