1、实用文档请求分页存储管理的实现写出方案实现代码（1）page类packagehomework;publicclassPage{privateintpagenumb;//页号privateintphysicsnumb;//物理块号privatebooleanstate;//状态位privateintvisitcount;//访问字段privatebooleanchange;//修改位privateintCRTaddress;//外存地址publicPage(){this.pagenumb=-1;this.physicsnumb=-1;this.s

2、tate=false;this.visitcount=0;this.change=false;this.CRTaddress=-1;}publicPage(intpagenumb,intphysicsnumb,booleanstate,intvisitcount,booleanchange,intCRTaddress){this.pagenumb=pagenumb;this.physicsnumb=physicsnumb;this.state=state;this.visitcount=visitcount;this.change=change
