石家庄铁道大学2022年秋季开学考试总结

  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;}
