This blog is a previous Java Multithreading (iii) Producer consumer model and the implementation of the method complement. The producer consumer model is implemented in three methods (lock, synchronized, blocking queue). The specific content is: The producer produces the random number (in order to facilitate the reading result, I limit the random number to 10 integers), the consumer reads and prints. 1 blo

JAVA basics: use Java to implement zip compression and decompression-Linux general technology-Linux programming and kernel information. The following is a detailed description. Due to limited network bandwidth, Data File compression is conducive to fast data transmission over the Internet, while also saving the server's external storage space.

Most JVMs have Java's hotswap feature, which most developers think is just a debugging tool. With this feature, it is possible to change the implementation of the Java method without restarting the Java process. A typical example is using the IDE to encode. However, HotSwap can implement this function in a production e
