Supposed I have a list of objects
[
Post(postid=1, title=testtitle1, post=test, created_at=null, updated_at=null),
Post(postid=2, title=testtitle2, post=test, created_at=null, updated_at=null),
Post(postid=4, title=testtitle4, post=test, created_at=null, updated_at=null),
]
and I have an incoming request like this:
[
Post(postid=4, title=zzzzzzz, post=testpost, created_at=null, updated_at=null)
]
How can I replace the old post with post id 4
Post(postid=4, title=testtitle4, post=test, created_at=null, updated_at=null),
with the new request
[
Post(postid=4, title=zzzzzzz, post=testpost, created_at=null, updated_at=null)
]
so that the list will become like this
[
Post(postid=1, title=testtitle1, post=test, created_at=null, updated_at=null),
Post(postid=2, title=testtitle2, post=test, created_at=null, updated_at=null),
Post(postid=4, title=zzzzzzz, post=testpost, created_at=null, updated_at=null)
]

There are many ways, one of them is :
posts.removeIf(p -> Objects.equals(newPost().getId(), p.getId()));
posts.add(newPost);

I recommend you to use Map data structure for your usecase, instead of using list:
Write code like below:
public class PostBase {
private Map<Integer,Post> posts = new HashMap();
public void addPost(Post post) {
posts.put(post.getPostid(), post);
}
public Post getPost(int id){
return posts.get(id);
}
}
If you still want to use list, you can remove existing element by find element by id and add new one like below(similar to answered by YCF_L):
Post newpost = new Post(4, "xxx", "tt", null, null);
postlist.removeIf((post)->post.getPostid() == newpost.getPostid());
postlist.add(newpost);

Just do,
for(Post post : posts) {
if(idOfIncomingRequest.equals(post.postid)) {
// update your data here
}
}

I have the following environment variable:
$ printenv

VCAP_SERVICES={"mariadbent":[{
"label": "mariadbent",
"provider": null,

},
"syslog_drain_url": null,
"volume_mounts": [
]
}]}
I can get the whole "pack" of data with System.out.println("VCAP_SERVICES: " + System.getenv("VCAP_SERVICES"));, but I would like to extract some field in the above output, like the username.
How could I do that?

Your VCAP_SERVICE hold an json. You can use an json parser to get a value from it.
Here is an example using Jackson, but there a more libs which can do this.
try{
String json = System.getenv("VCAP_SERVICES"); //NullPointerException, SecurityException
JsonNode jsonNode = (new ObjectMapper()).readTree(json); //IOException
if(jsonNode.has("mariadbent") && jsonNode.get("mariadbent").isArray()){
for(JsonNode elem : jsonNode.get("mariadbent")){
if(elem.has("credentials")){
JsonNode cred = elem.get("credentials");
if(cred.has("host")){
System.out.println(
cred.get("host").asText() //some-url-to-the-database.service
);
}else{ System.out.println("no host"); }
}else{ System.out.println("no credentials"); }
}
}else{ System.out.println("no mariadbent or not array"); }
}catch(Exception e){ e.printStackTrace(); }
For this you need lib Jackson Databind: https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind/2.9.9.3

I am trying to write a program which can create an output in JSON format, how would be best way of doing this? and programming languages?
This is an example output of JSON (expected output) which I need to input in the Name, Gender, Qualification and other attributes in a user friendly way during the execution of script. And in which outputs in following JSON format. Sorry, I am new in programming, but so much interested to learn Perl (or) Python (or) Java. What could be the best here?
Any suggestions?
P.S Sorry I am quite new to JSON as well, please apologize me for this basic one.
[
{
"Name":"Steven Mark",
"gender":"male",
"Qualification": {
"college":"Bachelor in Science",
"tech":"certified pro"
},
"contributions": [
{
"name":"biography",
"type":"book",
},
]
},
{
"Name":"Andrea Mark",
"Gender":"female",
"Qualifications": {
"college":"Bachelor in physics",
},
"contributions": [
{
"name":"my insights",
"type":"movie",
},
]
}
]

Virtually every language has a JSON library, including Perl.
use JSON;
my $data = [
{
"Name" => "Steven Mark",
"gender" => "male",
"Qualification" => {
"college" => "Bachelor in Science",
"tech" => "certified pro"
},
"contributions" => [
{
"name" => "biography",
"type" => "book",
},
]
},
{
"Name" => "Andrea Mark",
"Gender" => "female",
"Qualifications" => {
"college" => "Bachelor in physics",
},
"contributions" => [
{
"name" => "my insights",
"type" => "movie",
},
]
}
];
print(encode_json($data));

If you agree to use ANY programming language, i can suggest python. With its json lib you can do following (lines with # is comments):
# import lib
import json
# fill data into variable (this is list with dict objects inside):
data = [{"name":"john"},{"name": "bill"}]
# dump json
json.dumps(data)
Which will output your data as json.
You can start writing python using something from https://wiki.python.org/moin/BeginnersGuide

If you are going to use Python, you can try to use simplejson or json module to create a json object.
For example,
try:
import simplejson
except:
import json
data = dict(a=1,b=2)
with open("results.json", "w") as fp:
json.dump(data, fp, indent=3, encoding="utf-8")
For dumping, json is faster than simplejson (but not by an order of magnitude). For loading, simplejson is faster (but not by an order of magnitude).
You can check here for more detailed comparison between simplejson and json.

Any one help me to create mongo query for deleting where "name" : "gdfgdfgdfg" embedded document
The object stored as below in Mongo db.
{
"_id": ObjectId("50656f33a4e82d3f98291eff"),
"description": "gdfgdfgdfg",
"menus": [
{
"name": "gdfgdfgdfg"**,
"description": "dfgdgd",
"text": "dfgdfg",
"key": "2",
"onSelect": "yyy",
"_id": ObjectId("50656f3ca4e82d3f98291f00")
},
{
"name": "dfg",
"description": "dfgdfgdfgdf",
"text": "dfgdgf",
"key": "1",
"onSelect": "uuuu",
"_id": ObjectId("50656f44a4e82d3f98291f01")
}
]
}
Any one help me, I'm new to Mongo

In the JavaScript shell you can do this:
var query = {"_id": ObjectId("50656f33a4e82d3f98291eff")};
db.collection.update(query, {'$pull':{ menus: {name : 'gdfgdfgdfg'} } });
or use the Id.
db.collection.update(query, {'$pull': { menus: {"_id": ObjectId("50656f3ca4e82d3f98291f00")} } });
With the Java Driver should be something like this:
BasicDBObject query = new BasicDBObject("_id", new ObjectId("50656f33a4e82d3f98291eff"));
BasicDBObject docToRemove = new BasicDBObject("name", "gdfgdfgdfg");
BasicDBObject updateCommand = new BasicDBObject("$pull", new BasicDBObject("menus", docToRemove));
collection.update(query, updateCommand);

Mongo won't let you delete the embedded document. What you have to do is take the object from the collection, delete the one object in the list, and then save it back into the database.
obj = db.collection.findOne({"_id": ObjectId("50656f33a4e82d3f98291eff")});
menus = obj.menus.splice(0,1); // Or some other way to manually delete
// the one item in the list
db.collection.update({"_id": ObjectId("50656f33a4e82d3f98291eff")},
{$set: {menus: menus}});
It's complicated, see here.
EDIT: If you don't know the index, you can try this:
obj = db.collection.findOne({"_id": ObjectId("50656f33a4e82d3f98291eff")});
var i = 0;
for(i=0;i<obj.menus.length;i++) {
if(obj.menus[i].name === "gdfgdfgdfg")
break;
}
menus = obj.menus.splice(i,1);
db.collection.update({"_id": ObjectId("50656f33a4e82d3f98291eff")},
{$set: {menus: menus}});

$conditionArray=array("_id"=>ObjectId("50656f33a4e82d3f98291eff"));
$dataArray=array("description"=>"");
$db->$collectionName->update($conditionArray,array('$unset' =>$dataArray))->limit(1);
