StudentService方法的代码如下：
Java代码
package com.xzj.service;
import java.util.ArrayList;
import java.util.List;
import com.xzj.domain.Student;
public class StudentService {
public List find(){
List list=new ArrayList();
for(int k=1;k<10;k++){
list.add(k);
}
return list;
}
public Student findStudent(){
Student stu=new Student();
stu.setId(127);
stu.setName("小虎队");
stu.setAge(48);
return stu;
}
public List listStudent(){
List list=new ArrayList();
Student stu=null;
for(int k=1;k<6;k++){
stu=new Student();
stu.setId(k);
stu.setName("小猪"+k);
stu.setAge(23+k);
list.add(stu);
}
return list;
}
}
Student 的代码如下：
Java代码
package com.xzj.domain;
public class Student {
private int id;
private String name;
private int age;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
