We prefix the two blocks of code with the synchronized keyword, but notice crucially that we also mark them as being synchronized on a particular object— this in our example. That means that if we have multiple Counter objects, then different threads can update those different counters ...

Source code of the java.util.Collections class 37 This program has two performance problems that limit perform- ance scalability on a multicore machine. 1. Lock contentions will occur frequently at the synchronized blocks in Lines 24 and 36 in Figure 1. 2. Lock contentions will occur ...
Creating a message consumer to receive the messages. Instead of creating a message consumer in your source code, you associate the message-driven bean with a destination and a connection factory at deployment time. If you want to specify a durable subscription or use a message selector, you do...
