Question

package 老师;

import java.util.Scanner;

interface Person{
String name = "";
String gender="";
int age = 0;
public static void eat() {
System.out.println("吃饭");
}
abstract void play();
}
public class Teacher implements Person {
static String name;
int age;
String stitle;
public static void eat() {
System.out.println("我是"+name+"老师，我吃教师餐");
}
public void play() {
if(name.equals("张三")) {
System.out.println(name+"教授 教导课程：C语言");
}else if(name.equals("李四")) {
System.out.println(name+"教授 教导课程：java");
}else {
System.out.println(name+"教授 教导课程:jsp");
}
}
public class TestDuty {
Teacher str1 = new Teacher();
Scanner sc = new Scanner(System.in);
String nm = sc.next();
str1.play();
}
}
class Student implements Person {
String id;
String grade;
public void play() {
System.out.println("我是学生,我的职责是跟着老师认真学习,更主要是为了我自己而学习。");
}
public static void Student() {

}
public String getId() {
    return id;
}
public void setId(String id) {
    this.id = id;
}
public String getGrade() {
    return grade;
}
public void setGrade(String grade) {
    this.grade = grade;
} 

}

在TextDuty类里面创建对象用Teacherl里面的方法为什么错了

挡住34行的代码了，语法错误。
