String[] is always [Ljava.lang.String;@7638c30f

edited November 2017 in Library Questions

I am making a piece of code and I have a string[] declared called recs. I have lots of debug println(recs); in the code and they all return something that looks similar to [Ljava.lang.String;@7638c30f. I am using the networking library and sound library.

import processing.sound.*;
Server server;
String rec;
String[] recs = {"0"};
String[] tables = {};
String[] blank = {};
void settings() {
void setup(){
  server = new Server(this, 5204);
  println("recs debug:" + recs);
  for(int i = 0; i < loadStrings("data/data/tables.txt").length; i++) {
    for(int s = 1; s < split(loadStrings("data/data/tables.txt")[i], "$").length; s++) {
      tables = append(tables, split(loadStrings("data/data/tables.txt")[i], "$")[0] + split(loadStrings("data/data/tables.txt")[i], "$")[s]);
void draw(){
  Client client = server.available();
  if (client != null) {
    String incomingMessage;
    incomingMessage = client.readString(); 
    incomingMessage = incomingMessage.trim();
    recs = new String[] {};
    println("Recieved: " + incomingMessage);
    rec = incomingMessage;
    println("recs before:" + recs);
    recs = split(rec, "$");
    println("recs after:" + recs);

void refresh(){
  String[] table = {};
  table = loadStrings("data/data/" + recs[0] + ".txt");
  println("table:" + table);
  println("recs:" + recs);
  println("rec:" + rec);
  if(table[0] == "done"){
    saveStrings("data/data/" + recs[1] + ".txt", blank);
    for(int i = 1; i < (recs.length-1); i++) {
      table = append(table, recs[i]);
      saveStrings("data/data/" + recs[0] + ".txt", table);
void serverEvent(Server server, Client client) {
  println(" A new client has connected: "+ client.ip());


  • I know you tried, but...

    Format your code. Edit your post (gear on top right side of any of your posts), select your code and hit ctrl+o. Leave an empty line above and below your block of code. Details here:

    It is not difficult. You will get more attention if you format all your posts according to the provided link.


  • ah okay ctrl+o thanks

  • Answer ✓

    println("recs after:" + recs);

    is not the same as


    The first one will print the address reference of the object. The second one should print the content of the object. Give it a try and see if it does what you want.


  • thanks!! yeah, i guess if there's a string in front of it, it wouldn't want to print out the whole array behind it.

  • You also could make a function to return the content of the array:

    String getArrayAsText() {

    String result = „“;

    for(int i.....

    result =result + ..... + „\n“;

    return result;


    The „“ must be normal „“ but my @&€& iPhone is changing those
