java开学第一节课，我们亲爱的建民老师给我们准备了一套题目，在暑假时我们已经自学了一部分内容，但是突如其来的考试还是让我乱了阵脚，主要是熟练度不高，只完成了一些基础的项目，后面的项目没来得及写，最后成绩是9.5分，不到及格线。在那之后，我好好的研究了这一个题目，最后把所有要求完成了。以下是我的代码。
package work; class RoomInformation { private String roomno,stunno1,stunno2,stunno3,stunno4; private int hygienescore=0; RoomInformation(String roomno,String stunno1,String stunno2,String stunno3,String stunno4,int hygienescore){ this.roomno=roomno; this.stunno1=stunno1; this.stunno2=stunno2; this.stunno3=stunno3; this.stunno4=stunno4; this.hygienescore=hygienescore; } public void setRoomno(String r) {roomno=r;} public String getRoomon() {return roomno;} public void setStunno1(String s) {stunno1=s;} public String getStunno1() {return stunno1;} public void setStunno2(String s) {stunno2=s;} public String getStunno2() {return stunno2;} public void setStunno3(String s) {stunno3=s;} public String getStunno3() {return stunno3;} public void setStunno4(String s) {stunno4=s;} public String getStunno4() {return stunno4;} public void setHygienescore(int h) {hygienescore=h;} public int getHygienescore() {return hygienescore;} }
