The annotation processor places a file MyPatterns in the same package (by default in target/generated-sources). Inner classes are also supported. Special case: if the class name is $, the generated class name is just Patterns, without prefix.注释处理器将文件MyPatterns放在同一个包中(默认情况下...

The code above would remain correct even if theonSpinWaitmethod was not called at all. However on some architectures the Java Virtual Machine may issue the processor instructions to address such code patterns in a more beneficial way. Since: ...
Use what you know about the runtime platform or usage patterns. Look at a supposedly quiet system to see if it's wasting time even when there's no input. Keep small inheritance chains. Use stack (local) variables in preference to class variables. Merge classes. drawPolygon() is faster th...

In truth, many of these techniques were possible using nested types, via patterns like callbacks and handlers, but the syntax was always quite cumbersome, especially given that you had to explicitly define a completely new type even when you only needed to express a single line of code in the...
This approach performs faster than the nested loop algorithm for all but the smallest of Lists, and when the Lists are small the difference in speed is negligible. Deduping Lists in Java There are a variety of ways to remove duplicates from a List in Java. Which one should you use?
