thanks.

void setup() {

  size(300, 300);
  background(255);
  array();
}

void array() {

  int[][] arrayinit = {
    { 10, 5, 3, 55, 90 }, 
    {  9, 4, 2, 32, 22 }, 
    {  3, 8, 5, 79, 22 }, 
    {  3, 8, 45, 4, 2 }, 
    {  3, 22, 5, 44, 4 }
  };

  int rows = 5;
  int cols = 5;

  int[] sum = new int[cols];
  int[] sum2 = new int[rows];
  stroke(0);
  for (int c=0; c<cols; c++) { // for every column
    for (int r=0; r<rows; r++) { // for every row
      rect(40*r, 30*c, 40, 30);
      text(arrayinit[c][r], 40*r, 30*c); //dont know if this is right
      sum[c] += arrayinit[r][c]; // sum up the values per column
      sum2[r] += arrayinit[r][c];
    }
  }

  println(sum[0]); 
  println(sum[1]); 
  println(sum[2]); 
  println(sum2[2]);
  println(arrayinit[2][2]);
}

Any thoughts?

Thanks! ~jes

var paragraph = "hello <span style=\"color:blue;\">blueeee</span> adios"; txt = createP(paragraph);

For some reason when this is rendered in html, it introduces quotation marks:

<p> "hello " "span style=\"color:blue;\">blueeee</span>" " adios" </p>

Another alternative I though about would be to append word by word (with they specific style), but I'm not sure how to avoid the line break.

Any suggestions? Thanks!

I'm trying to load some images using the selectFolder function, the problem is that it looks like in Processing it needs to be with the normal bar, rather than the inverted one.

For example, the folder I chose looks like this: C:\Images and it would look like this: C:/Images

I tried to use the replaceAll function to override in the String, but it is not working.

Below is the example.

private String pathImg;

void setup() {
  selectFolder("Select a folder to process:", "folderSelected");  
}

void folderSelected(File selection) {
  if (selection == null) {
    println("Window was closed or the user hit cancel.");
  } else {
    pathImg = selection.getAbsolutePath();
    //String newPath = pathImg.replaceAll("\", "/");
    //pathImg = newPath;
    println("Path: " + pathImg);
  }
}

Thanks for listening

Plastic can’t be broken down by marine microorganisms, so while plastic debris gets smaller, it doesn’t go away. “Ocean confetti” has been found in every area and depth of the ocean, and we still don’t know much about its effects.

Code:

        void setup() {
              /*loading text into a string array (I have a lot, but only one has apostrophes and 
              quotation marks so I'll just use lines[4]*/

Many Thanks Guys!!

Matt.

I'm trying to remove the url's from strings, generated by tweets (using twitter4j) I've been trying all sorts of things with no luck.

So Let's say I have a string containing

"Hello, follow me! http://google.com"

or

"This is a tweet with an instagram photo https://instagr.am/blablabla"

I want to strip just the url from that string, but that url may be anything.

I've been trying things with regex, and other instructions I've found on the web, but I'm really lost. Could anyone point me in the right direction?

Returns result with comma "," like 3,63.

How to return result with period "." like 3.63.

                1
              1 2 1
            1 2 3 2 1
          1 2 3 4 3 2 1
        1 2 3 4 5 4 3 2 1
      1 2 3 4 5 6 5 4 3 2 1
    1 2 3 4 5 6 7 6 5 4 3 2 1
  1 2 3 4 5 6 7 8 7 6 5 4 3 2 1
1 2 3 4 5 6 7 8 9 8 7 6 5 4 3 2 1

void setup(){
     selectInput("Please find ffmpeg.bat", "launchStuff");
}

void launchStuff(File file){
     String filePath = file.getPath();
     launch("cmd /c start /w " + filePath);
}

The problem is that ffmpeg tends to download in Program Files (on Windows), which means that there are spaces in the file path. This causes the error "C:/Program" cannot be found. How do I deal with these spaces?

Thank you!

Is there an easy way to find-replace characters sequence in Processing? For example, as gsub function in R (https://stat.ethz.ch/R-manual/R-devel/library/base/html/grep.html)

 String a="14819021541";

I want for example that all the "1" will be change to something else (like "2"). How can I do that?

To be more specific , I would like include into the hashmap something like this: ("key1" : 10, "key2" :"home", "key3" : 15,3)

In all documentation I see that is mentioned that key must be string and values integer or float , but I didn't find something that say that values can be mixed inside the same hashmap.

Thanks.

but after I searching around I only found the way to count the string not alphabetical letters. is there's anyway to do it?

thank you.

String [] doc = loadStrings("testDoc.txt");
String name = "Wilson";

for (int i=0; i<doc.length; i++) { 
  doc[i].replaceAll("Johnson", name);
}

print(doc);

I'm working on projects, so I can not perform. Java mode and the android mode, how can I solve this problem.

I need your help too. Please share all your ideas. Before I could not get a clear answer to my problem. In fact, I could not ever get. I hope you can help.
