Sometimes we need to interrupt an executing thread at a specified point in time. For example, the thread that checks the sensor state every minute, and the rest of the time, the thread does not need to do anything. During this time, the thread does not need to use any of the computer's resources. After this time, and when the Java Virtual machine dispatches the thread, the thread continues to execute. To do

Simple use of Java transactions Java transactions are asked in some interviews. In the interview, the first thing we should answer is: The transaction can ensure the integrity and consistency of the data.

This rookie just contact Java a week, to its understanding is not deep, can only intuitively feel it. The personal sense and C + + are syntactically similar (actually just pair), first using two sample programs to show the face of Java programs. Example one: Classic GCD and LCM for two integer numbers. (The Euclidean algorithm is more typical) Package LCM and GC

introduced dynamic proxies and was often used to dynamically create proxies. The dynamic proxy for the JDK is very simple to use, but it has a limitation that objects that use dynamic proxies must implement one or more interfaces. If you want to broker an inherited class that does not implement an interface, you need to use the Cglib package.3) The Cglib is implemented by ASM, ASM is a Java bytecode manipulation framework that delves into the princip
