今天学了很多的关于方法的东西，还包括静态static.有点绕，还是有点模糊。

class  Demo1

{

public static void main(String[] args)

{

Teacher teacher = new Teacher();

teacher.name = "张浩";

teacher.major = "艺术";

teacher.class2 = "音乐";

teacher.age = 22;

teacher.show(4);

}

}

 

class Teacher

{

String name;

String major;

String class2;

int age;

void show(int choose)

{

 if (choose==1)

 {

System.out.println("teacher的名字是"+name);

 }else if (choose==2)

 {

 System.out.println("teacher的专业是"+major);

 

 }else if(choose==3)

{

 System.out.println("teacher的class2"+class2);

}else {

System.out.println(name+"\n专业方向"+major+"\n教授课程"+class2+"\n教龄"+age);

}

 

}
