Exception in thread "main" java.lang.Error: 无法解析的编译问题：

at thread1.main(thread1.java:90)

这是第90行 ：public static void main(String[] args){

照抄也能抄错了？跟书上一样啊55555555

Answer 1

对的，我的机子上都行了，但是有个小问题，你太粗心了：
public teacher(String teachername,String teachercode,String teachersexy,String teachercourse)
this.teachername=teachername;
this.teachercode=teachercode;
this.teachersexy=teachersexy;
this.teachercourse=teachercourse;
this.tostring();
}

看到没有，缺个{，所以导致了很多个错误报告
加上后就可以了
F:\java>java thread1

这个学生平均成绩是3月92
这个老师的薪水是1月2300

Answer 3

你真的抄错了。

teacher类中的构造方法
public teacher(String teachername,String teachercode,String teachersexy,String teachercourse)

少了一个"{"

Answer 4

teacher构造函数缺少{

Answer 5

看是不是有啥没有import
