问题 Is it possible in java by using something like ProcessBuilder to open gitbash, write a command (for example git status) and output the results?

I would like to stream my webcam live to the internet to a flash player or

问题 I created a class that extends InputStream so that I can keep count of the number of bytes being read and throw an exception if it exceeds a max limit that I define. Here is my class: public class LimitedSizeInputStream extends InputStream { private final InputStream original; private final long maxSize; private long total; public LimitedSizeInputStream(InputStream original, long maxSize) { this.original = original; this.maxSize = maxSize; } @Override public int read() throws IOException {

问题 I am attempting to run a Java server socket on a remote host which will regularly broadcast messages (determined by external processes) to all connected clients. The server socket is defined as: ServerSocket serverSocket = (ServerSocket) ((ServerSocketFactory)ServerSocketFactory.getDefault()).createServerSocket(3050); while (true) { Socket socket = serverSocket.accept(); remoteService.addSocket(socket); } Which will keep track of the socket connections in an array list. The method below will
