//Teacher.java
public class Teacher {
//4个String类型的私有字段Name、TeacherID、Address、Course

private String TeacherID;
private String Address;
private String Course;

public String getName() {
return Name;
}
public void setName(String name) {

public String getTeacherID() {
return TeacherID;
}
public void setTeacherID(String teacherID) {
TeacherID = teacherID;
}

public String queryCourse(String qryString){
if(qryString.equals(TeacherID)){
return Course;
}
return "";

//Test.java
public class Test {
public static void main(String[] args) {
Teacher t = new Teacher();
//设置该对象中的4个私有字段分别为：TeacherID=”001”、Name=”Peter”、Address=”Beijing”、Course=”OS”
t.setTeacherID("001");
t.setName("Peter");
t.setAddress("Beijing");
t.setCourse("OS");
String qryString = "001";
//显示“Teacher：此处为对象的Name，Course：此处为对象的课程”
System.out.println("Teacher:"+t.getName()+",Course:"+t.queryCourse(qryString));
}
}
