difference between the 5.sendRedirect () and Forward () methods?The Sendredirect () method creates a new request, and the forward () method simply forwards the request to a new target. After redirection (redirect), objects that were within the scope of the previous request are invalidated because a new request is generated, and after forwarding (forwarding), objects within the scope range of the previous request can be accessed. Sendredirect () is generally considered to be slower than forward

: Use node stream as input or output. The filter stream is created using an existing input stream or an output stream connection.6. Java SOCKET Programming, read the server several characters, and then write to the local display. After the client sends a connection request to the server, it passively waits for the server to respond.A typical TCP client is going through the following three steps:1. Create a Socket instance: the constructor establishes a TCP connection to the specified remote host

Test instructionsRobot Rob can move freely on a tree-like path. Given the beginning S and the end point of the tree path T, the robot Rob is moving from S to T. There are several movable obstructions on the tree path T. Because of the narrow path, any moment inThe path cannot hold 2 objects at any one time. Each step can move an obstacle or robot to an adjacent empty vertex. An effective algorithm is designed to move the robot from S to T with a minimum number of movements. Input File E
