This is my code:
JSONStringer result = new JSONStringer();
for (long i = start; i <= end; i = i + day) {
ttm.put("$gte", "" + i);
ttm.put("$lte", "" + (i + day));
//code code code
int count = statisticCollection.find(query).count();
try {
result.object().key("ttm").value(i).key("count").value(count);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
try {
result.endObject();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
I then get a JSONException. I also tried creating and ending the object with a different try-catch block, as below:
JSONStringer result = new JSONStringer();
try {
result.object();
} catch (Exception e) {
e.printStackTrace();
}
for (long i = start; i <= end; i = i + day) {
ttm.put("$gte", "" + i);
ttm.put("$lte", "" + (i + day));
//code code code
long count = statisticCollection.find(query).count();
try {
result.key("ttm").value(i).key("count").value(count);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
try {
result.endObject();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
and creating and ending the JSONStringer in the for loop itself, as follows:
JSONStringer result = new JSONStringer();
for (long i = start; i <= end; i = i + day) {
ttm.put("$gte", "" + i);
ttm.put("$lte", "" + (i + day));
//code code code
int count = statisticCollection.find(query).count();
try {
result.object().key("ttm").value(i).key("count").value(count).endObject();
} catch (JSONException e) {
e.printStackTrace();
}
What am I doing wrong?
Thanks.
You need to use an array:
JSONStringer result = new JSONStringer();
JSONWriter array = result.array();
for (long i = start; i <= end; i = i + day) {
ttm.put("$gte", "" + i);
ttm.put("$lte", "" + (i + day));
//code code code
int count = statisticCollection.find(query).count();
try {
array.object().key("ttm").value(i).key("count").value(count).endObject();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
try {
array.endArray();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

Okay what I am trying to achieve here is parsing a json string and separating its fields and assigning them to variables. Next I am creating a builder to send data to the elastic for indexing. But I am getting this error which is really bugging me. I am unable to move forward.

At (HERE) position erro keeps showing up..Cannot write a field name expecting a value.
Also is there a better way to achieve what I am trying to do here. thanks for the help.

I am able to get all other objects values I am unable to read the values array. I have written the code for it but its directly going to the catch block printing the error message "There is some error". Thnaks for the help.
Solved...Values was not an array it was an object....So here's what I did. It worked.
try {
String j2 = obj.getString("values");
JSONArray jContent = new JSONArray(j2);
for (int iterate = 0; iterate < jContent.length(); iterate++) {
JSONObject inner = jContent.getJSONObject(iterate);
String inner_label = (String) inner.get("label");
System.out.println(inner_label);
String val = (String) inner.get("value");
boolean sel;
try {
sel = (boolean) inner.get("selected");
} catch (JSONException j) {
sel = false;
}
System.out.print(inner_label);
System.out.print(" " + val);
System.out.println(" " + sel);
}
So I'm trying to use a client-server with a keyListener. When the messages "#left" or "#right" are sent to the server, it should update the graphical object and shift it to the left by calling the map.repaint() method. Instead, it shifts the object once and then no further responses happen. Posted below is the code. Can someone offer a solution?

The following Java code in two ways to copy files which more efficient? Want to be able to explain why, thank you.
By the way, I've tested the same file which size is about 300 megabytes. The speed of the first method as fast as the second one. But after tested more times, the result is differently.
One of my test result as below:
NO.1: Using transferFrom took 3396ms
NO.1: Using while took 3334ms
NO.2: Using transferFrom took 4239ms
NO.2: Using while took 3225ms
NO.3: Using transferFrom took 3906ms
NO.3: Using while took 4153ms
NO.4: Using transferFrom took 3100ms

I have a problem with my code.
It keeps on crashing when i have a blank editText field.
This bit of code is in the settings of my app and works the data fine but when there is a blank field it crashes the program.
Here's the code for it.
Please don't be harsh because it is my 1st android app. So if anyone knows how to solves the blank edit text field problem that would be greatly appreciated! (Any other comments on how to improve the app would be a help to).
Cheers

The above makes no sense at all.
Firstly task1 IS a string so there's no need to call toString() to convert it to one.
Secondly, your conditional statement (if) is checking to see if task1 has a length less than zero....think about it.
Thirdly, if it does have an impossible length less than zero you then call toString() on it again (with no variable to receive the impossible less than zero result) and you then try to set the text of your t1 EditText.
The chances are that your file reading is failing (probably because you only save the strings later in the onClick(...) method). Because your task strings will be null if the file reading fails then you need to test for null before trying to use them.
In other words you're doing this in your code...
String task1 = null;
To fix the bit of code I enclosed at the beginning, use...
if (task1 != null) {
t1.setText(task1);
}
else {
t1.setText(edit);
}
...but most importantly, make sure your files have the strings in them that you need to read.
