Writing foreach statement to filter Binance API results returns arbitrary data

I'm calling Binance API that returns a list of data. Now I want to filter the data to get some results and store using foreach statement in Java but it's been giving the result inclusively some arbitrary data result. I'm sure it is because of the way the foreach cascades.
What I'm trying to achieve is this:
private void pairscompared(){
List<Double> myPrice = new ArrayList<>();
List<TickerPrice> allPrices = client.getAll() aww;
for ( String btcPairsOnly: BTCPairsOnly()) {
for (String usdtPairsOnly: USDTPairsOnly()) {
if (btcPairsOnly.substring(0, btcPairsOnly.length()-3).equals(usdtPairsOnly.substring(0, usdtPairsOnly.length()-4))) {
for ( TickerPrice tickerPrice: allPrices ) {
if (btcPairsOnly.equals(tickerPrice.getSymbol()) ) {
myPrice.add(BTCUSDTPrice()/Double.parseDouble(tickerPrice.getPrice()));
}
if( usdtPairsOnly.equals(tickerPrice.getSymbol()) ) {
for ( Double myPriceBTC: myPrice) {
System.out.println(usdtPairsOnly +"-----" +myPriceBTC * Double.parseDouble(tickerPrice.getPrice()));
}
}
}
}
}
}
}
}
This is the kind of result I'm getting. It is supposed to return a single result per currency pair, but returning multiple per pair.

problem is in second if block
for ( TickerPrice tickerPrice: allPrices ) {
if (btcPairsOnly.equals(tickerPrice.getSymbol()) ) {
myPrice.add(BTCUSDTPrice().divide(tickerPrice.getPrice(), RoundingMode.HALF_UP));
}
if( usdtPairsOnly.equals(tickerPrice.getSymbol()) ) {
for ( BigDecimal myPriceBTC: myPrice) {
System.out.println(usdtPairsOnly +"-----" +myPriceBTC * Double.parseDouble(tickerPrice.getPrice()));
}
}
}
you print out all items from myPrices in every iteration when second if return true:
if( usdtPairsOnly.equals(tickerPrice.getSymbol()) )
What exactly you want to do?
Code should looks more like:
private void pairscompared(){
List<TickerPrice> myPrice = new ArrayList<>();
List<TickerPrice> allPrices = client.getAll();
for ( String btcPairsOnly: BTCPairsOnly()) {
for (String usdtPairsOnly: USDTPairsOnly()) {
if (btcPairsOnly.substring(0, btcPairsOnly.length()-3).equals(usdtPairsOnly.substring(0, usdtPairsOnly.length()-4))) {
for ( TickerPrice tickerPrice: allPrices ) {
if (btcPairsOnly.equals(tickerPrice.getSymbol()) ) {
myPrice.add(
new TickerPrice(btcPairsOnly, BTCUSDTPrice()/Double.parseDouble(tickerPrice.getPrice()))
);
}
if( usdtPairsOnly.equals(tickerPrice.getSymbol()) ) {
//TODO what you want to do when tickerPrice is usdtPairsOnly
}
}
}
}
}
for ( TickerPrice myPriceBTC: myPrice) {
System.out.println(myPriceBTC +"-----" +myPriceBTC.getPrice()));
}
}
}

How to manipulate parameters sending to remote object in CORBA using interceptors

New to CORBA but could establish remote method invoking from a client to server. When using interceptors and try to encrypt parameters for the remote method, it throws below
Failed to initialise ORB: org.omg.CORBA.NO_RESOURCES: vmcid: OMG minor code: 1 completed: No org.omg.CORBA.NO_RESOURCES: vmcid: OMG minor code: 1completed: No at com.sun.corba.se.impl.logging.OMGSystemException.piOperationNotSupported1(Unknown Source)
at com.sun.corba.se.impl.logging.OMGSystemException.piOperationNotSupported1(Unknown Source)
at com.sun.corba.se.impl.interceptors.ClientRequestInfoImpl.arguments(Unknown Source)
at orb.CustomClientInterceptor.send_request(CustomClientInterceptor.java:23)
From Interceptors I'm trying to access arguments and encrypt them like below.
public void send_request( ClientRequestInfo ri )
{
System.out.println( ri.arguments() );
System.out.println( "Arguments.." );
logger( ri, "send_request" );
}
But cannot even access them, it throws above error. Intercepting methods are calling fine. Could you guide me with some code or a link.
Thanks in Advance

I found the answer and if someone hits this in future..
We cannot manipulate parameters in interceptors unless the call to CORBA object is either DII or DSI call. So first you need to make a call in either of these. I did it via DII. code is as follows.
//-ORBInitialPort 1050 -ORBInitialHost localhost
Properties p = new Properties();
p.put("org.omg.PortableInterceptor.ORBInitializerClass.orb.InterceptorORBInitializer", "");
//ORB orb = ORB.init(args, p);
String[] orbArgs = { "-ORBInitialHost", "localhost", "-ORBInitialPort", "1050" };
//NO_NEED ORB orb = ORB.init( orbArgs, null );
orb = ORB.init(orbArgs, p);
//objRef = orb.resolve_initial_references( "NameService" );
//ncRef = NamingContextExtHelper.narrow( objRef );
//DII Additional configs
org.omg.CORBA.Object ncRef = orb.resolve_initial_references ("NameService");
NamingContext nc = NamingContextHelper.narrow (ncRef);
NameComponent nComp = new NameComponent ("ABC", "");
NameComponent [] path = {nComp};
objRef = nc.resolve (path);
Then do the DII call, I have some mixed code here but you will understand what to do
NVList argList = orb.create_list (valueMap.size());
for (Map.Entry<String, String> entry : valueMap.entrySet()) {
Any argument = orb.create_any ();
argument.insert_string (entry.getValue());
argList.add_value (entry.getKey().toLowerCase(), argument, org.omg.CORBA.ARG_IN.value);
}
//Result
Any result = orb.create_any ();
result.insert_string( null );
NamedValue resultVal = orb.create_named_value ("result", result, org.omg.CORBA.ARG_OUT.value);
//Invoking Method
Request thisReq = objRef._create_request (null, methodName, argList, resultVal);
thisReq.invoke ();
//Extract Result
result = thisReq.result().value ();
Now from the interceptors you will need to filter the DII call only and then access the parameters like below.
public void send_request( ClientRequestInfo ri )
{
if(ri.operation().equals( "processPayment" ))
{
System.out.println( "################# CLIENT SIDE ###############" );
int count = 0;
for(Parameter param : ri.arguments())
{
System.out.println( "Arg : "+count );
System.out.println( param.argument.extract_string());
param.argument.insert_string( EncryptionDecryption.encrypt( param.argument.extract_string() ) );
count++;
}
}
System.out.println( "Arguments.." );
logger( ri, "send_request" );
}

NOTE: this game uses a custom class launcher, + i use the forge api on it.
I looked at the cout debugs and looks like the cout's stop at :
cout << "FID: " << fid << endl;
After that no more cout's get called. then the game stops responding.
Thank you for reading and hopefully i was descriptive enough.
EDIT: The whole code stops the game minecraft from responding after some time or instantly idk its random.
I use standard injection with extreme injector for now.

Edit: This is to better explain everything:
I inject this dll into the game after everything in the game has initialized.
The games uses a custom class loader(LaunchClassLoader) i try to retrieve a instance of that, to do so i get the FMLLaunchHandler there i get a instanceof FMLLaunchHandler then from that instance i get classLoader and from that instance i use the classLoaders findClass to get the class.
Someone told me that i need to get a initialized version of a class to use non static methods or get non static fields.
I use a injector called extreme injector for now and use standard injection which is loadlibrary.
I also do not create my own vm, i attach to the running minecraft vm and get the env from that thru a dll and init function handles the attaching.
Thanks for reading, have nice day.

Downloading artifacts from remote maven repo programmatically

I am using Aether utility library to manage deppendencies. When I try to download the transitive dependencies for a maven artifact I get a
java.io.IOException: Invalid Content-Range header for partial download
error. I am using almost the same code from the aether example here https://github.com/eclipse/aether-demo/blob/master/aether-demo-snippets/src/main/java/org/eclipse/aether/examples/ResolveTransitiveDependencies.java
/**
* Resolves the transitive (compile) dependencies of an artifact.
*/
public class ResolveTransitiveDependencies
{
public static void main( String[] args )
throws Exception
{
System.out.println( "------------------------------------------------------------" );
System.out.println( ResolveTransitiveDependencies.class.getSimpleName() );
RepositorySystem system = Booter.newRepositorySystem();
RepositorySystemSession session = Booter.newRepositorySystemSession( system );
Artifact artifact = new DefaultArtifact( "org.eclipse.aether:aether-impl:1.0.0.v20140518" );
DependencyFilter classpathFlter = DependencyFilterUtils.classpathFilter( JavaScopes.COMPILE );
CollectRequest collectRequest = new CollectRequest();
collectRequest.setRoot( new Dependency( artifact, JavaScopes.COMPILE ) );
collectRequest.setRepositories( Booter.newRepositories( system, session ) );
DependencyRequest dependencyRequest = new DependencyRequest( collectRequest, classpathFlter );
List<ArtifactResult> artifactResults =
system.resolveDependencies( session, dependencyRequest ).getArtifactResults();
for ( ArtifactResult artifactResult : artifactResults )
{
System.out.println( artifactResult.getArtifact() + " resolved to " + artifactResult.getArtifact().getFile() );
}
}
}

I resolved this problem by removing the artifact jars in local repository, however I'm still not sure why this exception happens, it seems to occur when the network is not stable. Hope it will help.

One error for sure is that you increment i two times!!!
System.out.println("\n07)..................."+i++ + o); // one
pstmt.setObject(i++, o); // two
This means that you don't set the even indices, just the odd ones: 1, 3, 5...
This should correct this error:
System.out.println("\n07)..................."+i + o);
pstmt.setObject(i++, o); // only once, and after the evaluation!
EDIT
*Second, but also big mistake*
} catch(SQLException e) {
System.out.println("\n11)************* :"+e); //WTF?
//handle the error...
}
excuse me for shouting, this has to happen now!
Please, for our and your (future) colleagues' mental health's sake, DO NOT EVER DO THIS AGAIN!
Printing exceptions must happen in one of two ways:
logger.error("message", e);
e.printStackTrace();
As these reserve the stack trace, and thus enable proper debugging of the code
but should never, ever, ever, never! happen in any of these ways:
System.out.print(e)
System.out.print(e.getMessage)
System.out.print("message " + e.getMessage)
logger.error(e.getMessage)
So correctly this should be:
} catch(SQLException e) {
System.out.println("\n11)************* :"+e.getMessage());
e.printStackTrace();
//TODO: handle the error...
}
By the way: using proper logging like log4j is well worth the time! It consumes much more time to clean up all the System.out.*, than to set a proper loglevel...
EDIT2
As for the SQL error:
String sql = "INSERT INTO files_1 VALUES(?)";
This SQL line tells the DBMS that it will have one parameter to deal with. The table has 3 columns, so you need to specify 3 values. Either constants, or parameters (by using ?). So you should have:
String sql = "INSERT INTO files_1 VALUES(?,?,?)";

As indicated by your error
java.sql.SQLException: Invalid argument value: java.io.NotSerializableException
you're trying to set a value with a parameter that's not serializable in this line:
pstmt.setObject(i++, o);
Please make sure that all of your values are either primitives or values that can be mapped to database columns like String or Date.
You can find out which data you're trying to set by putting in a line like this (using a logging framework or System.out.println:
System.out.println("setObject: " + o + ", Class: " + o.getClass());
