correctly deserialized phenomenon.There are such concentrations that need to be discussed:1. If you modify a class to modify only the method, deserialization is not affected. No need to specify SERIALVERSIONUID value2, if you modify the class only static field or transient field is modified, then deserialization is not affected. You do not need to specify a Serialversionuid value.3. Modifying a non-static field non-transient field when modifying a class may cause the serialization version to be

Java implementation of large file download, based on HTTP, control God horse will not say. Idea: The download file is nothing but to read the file and then write the file, mainly these two steps, the main difficulty: 1. Read the file, is the hard disk to the memory process, due to the JDK memory limit, can not read too large. 2. Write a file, is to respond to the

At this point, you need to verify the legality of the Java program. It is time-consuming to verify this, but if we are good at using each download resource (larger, such as a map or game update), if not just
