Convert the attached C++ code to working Java code. Be judicious in the change that you make. This assignment is not about re-writing or improving this code, but rather about recognizing the differences between C++ and Java, and making the necessary coding changes to accommodate how Java does things. PLEASE DO NOT use a built-in Java QUEUE (or any other) container. Additional resources for assignment: #include
