java 怎么获取网站中所有的a标签，以及a标签里面的内容
Document doc = Jsoup.connect("").get();
Elements links = doc.select("a[href]"); // a with href
Jsoup了解一下。
高分求java代码 （认真回答还有悬赏）
按你现在说的这个内容，我觉得三个类就能表现出来，我写了一下，你看看能不能满足你的要求：
/**
* 运动员信息
* @author songfeng163
*/
public class PlayerState {
private String lx; //运动类型
private String xing; // 姓
private String ming; // 名
public String getLx() {
return lx;
}
public void setLx(String lx) {
this.lx = lx;
}
public String getXing() {
return xing;
}
public void setXing(String xing) {
this.xing = xing;
}
public String getMing() {
return ming;
}
public void setMing(String ming) {
this.ming = ming;
}
//返回姓名信息
@Override
public String toString() {
return xing+ming;
}
}
/**
* 运动员得分信息
* @author songfeng163
*/
public class SoccerPlayerStats {
private PlayerState player; //运动员信息
private double spointsScored; //点球得分
private double assists; //助攻得分
private double penaltyKickRate; //罚球得分概率
public PlayerState getPlayer() {
return player;
}
public void setPlayer(PlayerState player) {
this.player = player;
}
public double getSpointsScored() {
return spointsScored;
}
public void setSpointsScored(double spointsScored) {
this.spointsScored = spointsScored;
}
public double getAssists() {
return assists;
}
public void setAssists(double assists) {
this.assists = assists;
}
public double getPenaltyKickRate() {
return penaltyKickRate;
}
public void setPenaltyKickRate(double penaltyKickRate) {
this.penaltyKickRate = penaltyKickRate;
}
//返回分数信息
@Override
public String toString() {
return "** PLAYER ADDED **"+ player.toString()+"; Points:"+ spointsScored + "; Assists: "+ assists +"; Penalty Kick %:" + penaltyKickRate;
}
}
这里是主类：
import java.util.Scanner;
import java.util.List;
import java.util.ArrayList;
/**

public class MyMain {
//添加方法
public ListSoccerPlayerStats add(ListSoccerPlayerStats list){

System.out.println("请输入运动类型：足球，高尔夫，田径：");
player.setLx(in.next());
System.out.println("请输入姓：");
player.setXing(in.next());
System.out.println("请输入名：");

//显示方法
public void show(ListSoccerPlayerStats list){

for(SoccerPlayerStats score:list){

}
bw.flush();
bw.close();
}catch(Exception ex){
ex.printStackTrace();
}
System.out.println("** 1 RECORD SAVED TO "+fileName+" **");
return list;
}
public static void main(String[] args) {
MyMain myMain=new MyMain();
Scanner in=new Scanner(System.in);
//如果像你说的是数组的话，数据没有办法动态变化，所以我用了list
ListSoccerPlayerStats list=new ArrayListSoccerPlayerStats();
String cz="QUIT"; //默认的操作为退出
System.out.println("下面如何操作（ADD, REMOVE, SHOW, SAVE, QUIT）？");
String czin=in.next(); //输入数据
cz=czin.toUpperCase(); //转换成大写
while(!cz.equals("QUIT")){ //不是退出
if(cz.equals("ADD")){ //添加数据
list = myMain.add(list);
}else if(cz.equals("REMOVE")){ //删除数据

java作业求1到100以内即是3的倍数又是5的倍数的数，并输出
for(int i＝1;i＜＝100;i＋＋)｛
if(i%3=0i%5=0){
system.out.println(i);
}
｝
自己调整语法，这个有中文字符
