circumstances to 8 screen around to display. This makes it difficult to read a program or modify a program. It is therefore advisable to extract the block that completes the comparison of independent functions as a single function. A block that accomplishes the same or similar function is extracted independently of a sub-function. It can be found that the simpler the upper-level function is, the more specific work is done by invoking a few sub-functions, the more the underlying function complet

due to the time and space required for the copy-on-write operation. Second, your program does not need collection to have the most up-to-date information, iterator only with collection information at the time of creation.
consider using multiple collection.Although some collection have minimal synchronization, these synchronization processes are problematic when there are multiple threads involved. Consider using

During the Spring Festival read the next "java:the complete Reference" found this writing in simple, I think a question, the book a lot of content we also know, but why we can not write such a book, so comprehensive, so systematic, so simple and easy to understand. Have to admire Herbert Schildt programming skills, need to mention is Herbert Schildt wrote a lot of Java and C, C + + books, he is the C, C + +, Java

In Java, the lock that follows the Synchronized keyword is freed when the thread leaves the range of the synchronization block, even if it is out of scope because of an exception. Therefore, when using the synchronized keyword in Java, the exception causes the deadlock to occur without releasing the lock, which never occurs.
Lock Interace in place of the synchronized keyword,
