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
