The stream classes in java.io are a series of filters which can be
combined to get the functionality you desire. The DataInputStream has
a readLine() method, so to emulate gets() use:
DataInputStream in = new DataInputStream(System.in);
String line = in.readLine();
To emulate fgets() try (as in, I didn't copy this code from a working
class, so it may be off):
FileInputStream fis = new FileInputStream("my file name");
BufferedInputStream bis = new BufferedInputStream(fis);
DataInputStream in = new DataInputStream(bis);
String line = in.readLine();
That last bit is normally written here as:
DataInputStream in = new DataInputStream(
new BufferedInputStream(
new FileInputStream("my file name")));
Which better demonstrates the filtering, but may be too lisp-ish for some.
