JEP 445:Unnamed classes and instance main methods (preview).This JEP offers a smooth on-ramp to Java so educators can introduce programming concepts in a gradual manner. It does so by reducing the boilerplate and ceremony so that students can write their first programs without needing to unders...
String buffers are safe for use by multiple threads. The methods are synchronized where necessary so that all the operations on any particular instance behave as if they occur in some serial order that is consistent with the order of the method calls made by each of the individual threads invo...
