how to Send very large String from Java to Arduino through serial port

I am trying to send many strings in one time from java to arduino in a list of strings. but arduino cant catch them all (catched me just 3)

How can i get all the strings from java to arduino ?

Java code

chercherPort("COM11");
             connecterPort();
             Thread.sleep(4000); 

            output.write("@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0".getBytes());
            output.write("@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0".getBytes());
            output.write("@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0".getBytes());
            output.write("@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0".getBytes());
            output.write("@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0".getBytes());
            output.write("@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0".getBytes());
            output.write("@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0".getBytes());
            output.write("@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0".getBytes());
            output.write("@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0@1#240#-120%140#120#-240@0".getBytes());

            fermerPort();

Arduino code

void myReadSerialStrv2(int *Autorise,int *Nombresignal,String *StringSignal) {

  while (Serial.available() > 0) 
  {
   String readmessage = Serial.readString();


    Serial.println(readmessage.length());

    StringSignal[Nombresignal[0]]=readmessage; //List of string

    Nombresignal[0] =Nombresignal[0]+1;

  }
}

Do you know a good way to send a very large list of string to Arduino ?

Because i want to get all the list in arduino then i will call function in arduino that will use this list .

If the string is able to fit within the Arduino memory you should be able to receive it using the 2nd or 3rd example inSerial Input Basics

If it is too big to be completely stored in the Arduino you will obviously need to analyse it as it arrives and you will need to explain what analysis you want to do.

The String class (large S) is not suitable for the small memory of an Arduino - it can cause memory problems. Use c strings (small s).
