Java compressed file tool class ZipUtil usage code example, tool class ziputil This example uses the Java Zip input/output stream to compress and decompress files.

each update, it is necessary to download and update resources over the network and automatically update the system.How to implement: Below is a simple example of JAVA Implementation for delayed download of resources. Load the two sample programs in my previous blog and run one of them. (PS: Since the resources loaded in this example are jar, dynamic class loadin

interface is a manufacturer (marker) interface. That is, the interface does not need to implement any methods for the class to implement it. It is used primarily to inform the Java Virtual Machine (JVM) of the need to serialize an object. For this, there are several points we need to be clear: Not all classes can be serialized, under CMD, we enter Serialver Java.net.Socket, we can get the information that the socket is serializable, actually the s

thinking from Java single example and single case Objective A few days ago accidentally saw an article, talked about the cliché of a single example, holding a review of the mentality points in, or those familiar with the content, but found himself thinking of the angle changed, before more is to remember, only stay on the surface, and now more is to think why

converted to a running state: When this thread gets the processor resources; The run state is converted to a ready state: When this thread actively invokes the yield () method or loses the processor resources during the run process. The run state is converted to a dead state: When this thread thread execution completes or an exception occurs. It is important to note here that when the yield () method of the thread is invoked, the thread transitions from the run state to the ready state, but
