摘要：public XdlUser(int id, String name, int age, double salary) {。案例需求：定义一个javaBean叫XdlUser，有四个字段int id、String name、int age、double salary。
案例需求：定义一个javaBean叫XdlUser，有四个字段int id、String name、int age、double salary。写一个jsp页面，在页面中构建一个列表对象，里面存放几个XdlUser类型的对象。
案例实现：
● XdlUser类
package com.xdl.bean;
public class XdlUser {
public XdlUser(int id, String name, int age, double salary) {
super();
this.id = id;
this.name = name;
this.age = age;
this.salary = salary;
}
public XdlUser() {
super();
}
@Override
public String toString() {
return "XdlUser [id=" + id + ", name=" + name
+ ", age=" + age + ", salary=" + salary + "]";
}
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;
}
public double getSalary() {
return salary;
}
public void setSalary(double salary) {
this.salary = salary;
}
private int id;
private String name;
private int age;
private double salary;
}
