Having worked on art of some of the most well-known DC characters in comic book history, he recently did pencils for DC’s latest version of the Doom Patrol. Matthew is currently working on Ghost Rider for Marvel Comics, with whom he has signed an exclusive two-year deal.<br /><br />Matthew has lived in Portland for the past 13 years, just above an art gallery in the heart of downtown. He loves to walk around this fair city (mainly because he sold his car and needed to force himself to exercise). He’s a native Oregonian and that’s saying something. For the past 11 years he’s met Greg Rucka for coffee every Wednesday pretty much without fail at the same place (we pretty much carved our names in the table). Matthew was also one of the original founders of Mercury Studio (now Periscope Studio); he got his start at Studiosaurus.<br /><br />He still reads comics, loves what he does, and works very hard. Loves to meet new people, but is really quiet (and has great hair).",

"biotext": "Sean Williams was born in the dry, flat lands of South Australia, where he still lives with his wife and family. He has been called many things in his time, including “the premier Australian speculative fiction writer of the age†(Aurealis), the “Emperor of Sci-Fi†(Adelaide Advertiser), and the “King of Chameleons†(Australian Book Review) for the diversity of his output. That award-winning output includes thirty-five novels for readers all ages, seventy-five short stories across numerous genres, the odd published poem, and even a sci-fi musical.<br /><br />He is a multiple recipient of the Aurealis and Ditmar Awards in multiple categories and has been nominated for the Philip K. Dick Award, the Seiun Award, and the William Atheling Jr. Award for criticism. He received the “SA Great†Literature Award in 2000 and the Peter McNamara Award for contributions to Australian speculative fiction in 2008.<br /><br />On the sci-fi front, he is best-known internationally for his original award-winning space opera series as well as several novels set in the Star Wars universe, many co-written with fellow-Adelaidean Shane Dix. These include the Astropolis, Evergence, Orphans and Geodesica series, and the computer game tie-in The Force Unleashed–the first such adaptation ever to debut at #1 on the New York Times bestseller list. A series for young readers, The Fixers, pitted an increasingly lost protagonist against zombies, cyborgs, and vampires across numerous universes. His most recent releases in the Star Wars universe are The Old Republic: Fatal Alliance and The Force Unleashed II.",

"biotext": "Richard Dean Anderson is probably best known as MacGyver, the clever and inventive nonviolent hero who solved problems in his own unique way for seven successful seasons on ABC. In his roles before and since, this gifted actor has continued to demonstrate his remarkable talent and versatility.<br /><br />Richard was born on January 23, 1950 in Minneapolis, Minnesota. His father, Stuart Anderson, taught English, drama, and humanities at a local high school, and is an accomplished jazz bassist. His mother, Jocelyn, is an artist, talented in both painting and sculpture. Richard is the eldest of four sons. He and his brothers, Jeffrey Scott, Thomas John, and James Stuart, grew up in the Minneapolis suburb of Roseville, where Richard developed early interests in sports, the arts, music, and acting.<br /><br />Like many boys growing up in Minnesota, Richard dreamed of becoming a professional hockey player. However, at the age of 16, he broke both arms, in separate accidents three weeks apart, while playing in high school hockey games. He put aside his dreams of playing professionally, though he still harbors a deep love for the sport. Richard talks of his restlessness growing up, his early desire to explore, and his adventures hitchhiking and hopping freight trains. At the age of 17, he took a 5641 mile bicycle trip from his home in Minnesota through Canada and Alaska, an experience which was sparked by his sense of adventure and discovery, but which also gave him a more centered sense of direction.",

I have object class named Name, and I want to put all the data of the name(perth) jsonobject as a single object of the Name class. But it is not adding data in the arraylist correctly, more clearly the guestid, guestname etc tag values are being saved but overwrites the previous one. Here is my parsing code:
我有一个名为Name的对象类,我想将名称(perth)jsonobject的所有数据作为Name类的单个对象。但是它没有正确地在arraylist中添加数据,更清楚的是guestid,guestname等标记值被保存但是覆盖了前一个。这是我的解析代码:
public ArrayList<Guest> parseInitiator() throws ClientProtocolException,
IOException, JSONException {
InputStream is = new FileInputStream(new File(Url));
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
String mResponse = new String(buffer);
JSONObject first = new JSONObject(mResponse);
JSONArray firstarray = first.getJSONArray("location");
ArrayList<Guest> parsedData = new ArrayList<Guest>();
for (int i = 0; i < firstarray.length(); i++) {
JSONObject jonj = firstarray.getJSONObject(i);
name = jonj.getString("name");
JSONArray confarray = jonj.getJSONArray("conferencelocation");
locationname = new String[confarray.length()];
for (int j = 0; j < confarray.length(); j++) {
JSONObject conobbj = confarray.getJSONObject(j);
locationname[j] = conobbj.getString("locationname");
JSONArray guestarray = conobbj.getJSONArray("guests");
guestid= new String[guestarray.length()];
guestname= new String[guestarray.length()];
time= new String[guestarray.length()];
largeimg= new String[guestarray.length()];
smallimg= new String[guestarray.length()];
biotext= new String[guestarray.length()];
autographs= new String[guestarray.length()];
photographs= new String[guestarray.length()];
genre= new String[guestarray.length()];
for (int k = 0; k < guestarray.length(); k++) {
JSONObject guestobbj = guestarray.getJSONObject(k);
guestid[k] = guestobbj.getString("guestid");
guestname[k] = guestobbj.getString("guestname");
time[k] = guestobbj.getString("time");
largeimg[k] = guestobbj.getString("largeimg");
smallimg[k] = guestobbj.getString("smallimg");
biotext[k] = guestobbj.getString("biotext");
autographs[k] = guestobbj.getString("autographs");
photographs[k] = guestobbj.getString("photographs");
genre[k] = guestobbj.getString("genre");
JSONArray linkar = guestobbj.getJSONArray("links");
arlink= new String[linkar.length()];
arurl= new String[linkar.length()];
for (int l = 0; l < linkar.length(); l++) {
JSONObject linkobj = linkar.getJSONObject(l);
arlink[l] = linkobj.getString("linkname");
arurl[l] = linkobj.getString("url");
}
}
}
parsedData.add(new Guest(name,locationname, guestid, guestname, time, largeimg, smallimg, biotext,
autographs, photographs, genre,arlink, arurl));
}
return parsedData;
}
Can anyone make me clear about the mistake I have made?
谁能让我清楚我犯过的错误?

So here is my solution:
所以这是我的解决方案:
JSONObject first = new JSONObject(mResponse);
JSONArray locArr = first.getJSONArray("location"); // contains one object
JSONObject locArrObj = locArr.getJSONObject(0); // cotains one "out" array
JSONArray conferenceLocArr = locArrObj.getJSONArray("conferencelocation");
// this array has two objects and each object has array
JSONObject o = null;
JSONArray arr = null;
for (int i = 0; i < conferenceLocArr.length(); i++) {
o = conferenceLocArr.getJSONObject(i); // it has one array
arr = o.getJSONArray("guests");
// do your work with Stage 1 and guests
// and for second object for Stage 2 and guests.
}
