谁帮我做下这1道java题

public class Test {

public static void main(String args[]) {

Test t = new Test();

Student s = t.new Student();

s.talk();

}

abstract class Person {

String name = "tom", age = "20", like = "play football";

abstract void talk();

}

class Student extends Person {

String school;

@Override

void talk() {

System.out.println("my name is " + name + ",i am " + age

+ " years old," + "i like " + like + ".");

}

}

}

下面是运行结果：

abstract class Person
{
	public String name;
	public int age;
	public String like;
	public abstract void talk();
	
} 

class Student extends Person
{
	public Student(String name, int age, String like)
	{
		this.name = name;
		this.age = age;
		this.like = like;
	}

	public void talk()
	{
		System.out.println("我的名字" + name + "," + "年龄" + "age" + "," + "喜欢的东西" + like);
	}
}



public class Test
{
	public static void main(String args[])
	{
		Person p = new Student("tom",18,"football");
		p.talk();
		
	}
}

abstract class Person {
private String name;
private int age;
private String like;

protected String getName() {
return name;
}

protected void setName(String name) {
this.name = name;
}

}

protected void setAge(int age) {

}

return like;
}

protected void setLike(String like) {

}

protected abstract void talk();
}

class Student extends Person {

private String school;

@Override
protected void talk() {
StringBuffer sb = new StringBuffer();
sb.append("name: " + getName() + "\n");
sb.append("age: " + getAge() + "\n");
sb.append("like: " + getLike());
System.out.println(sb);
}

public String getSchool() {
return school;
}

public void setSchool(String school) {
this.school = school;
}

}

public class Test {

public static void main(String[] args) {
Person p = new Student();
p.setName("小明");
p.setAge(11);
p.setLike("足球");
p.talk();
}
}
