JSTL表格案例
定义一个Member类 将数据存储在list集合 并将数据打印在页面上以表格的形式
Member类
package utils;
import java.text.SimpleDateFormat;
import java.util.Date;
public class Member {
private String name;
private String gender;
private int age;
private Date date;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public Date getDate() {
return date;
}
public void setDate(Date date) {
this.date = date;
}
public Member() {
}
public Member(String name, String gender, int age, Date date) {
this.name = name;
this.gender = gender;
this.age = age;
this.date = date;
}
public String getDateformat()
{
SimpleDateFormat sdf = new SimpleDateFormat("yyyy年MM月dd日 HH时mm分ss秒");
String format = sdf.format(date);
return format;
}
}
