这个是我自己做的，但是在buleJ上编译时有出现错误，可以帮我指出错误之处吗？
public class person1 {
private static String name;
private static String sex;
private static int age;
public person1() {
this.name = "王明";
this.sex = "男";
this.age = 18;
}
public void showMe() {
System.out.print("名字：" + this.name + " 性别：" + this.sex + " 年龄：" + this.age + " ");
}
}
public class Student extends person1 {
private static String department;
private static String specialty;
Student(String name,String sex, int age, String department,String specialty)
{
super(name,sex, age,department,specialty);
this.department = department;
this.specialty = specialty;
}
public void ShowStudent() {
super.ShowStudent();
System.out.println("系别：" + department + " 专业：" + specialty );}}

一堆快捷键就可以操作完成了
