Today to learn the cloning of Java objects, in writing code, sometimes we write: Object 1 = Object 2, that is, Object 2 is assigned to object 1, but there is a problem, if we modify the property value of Object 2, the same property value of object 1

The Right value reference (and its supported move semantics and perfect forwarding) is one of the most significant language features that c++0x will join, which can be seen from the list of the features in the C + + state of the evolution. from a

Java clone () method instructions, javaclone One advantage of Java is that it removes the pointer concept, but many programmers often ignore the difference between objects and references in programming, in addition, Java cannot solve the problem of

 1) first, the difference between what is a value assignment and what is initialization.2) the overload in the program uses reference transfer. The reason is: ① as we all know, parameters passed with values will generate a copy in the function to be
