A framework written in Java for implementing high-level and dynamic languages, compiling them into Java bytecodes.
An implementation of Scheme, which is in the Lisp family of programming languages. Kawa is a featureful dialect in its own right, and additionally provides very useful integration with Java. It can be used as a “scripting language”, but includes a compiler and all the benefits of a “real” programming language, including optional static typing.
對于給定的一組進程,采用優先級加時間片輪轉法進行調度。設有一個就緒隊列,就緒進程按優先數(優先數范圍0-100)由小到大排列(優先數越小,級別越高)。當某一進程運行完一個時間片后,其優先級應下調(如優先數加3),試對如下給定的一組進程給出其調度順序。每當結束一進程時要給出當前系統的狀態(即顯示就緒隊列)。這里,進程可用進程控制塊(PCB)表示為如右表所示。
進程名 A B C D E F G H J K L M
