Hi guys,  
I’m going crazy on something really stupid, but I just can not solve it.  
I would like to wrap after I’ve found a specific character.  
the code I am using is this:

```auto
String[] lines; 
String randText;

void setup() {
  size(1280, 720);
  lines = loadStrings("howl.txt");
  background(0);
  frameRate(1);
}

void draw() {
  //fill(0, 255);
  //rect(0, 0, width, height);
  //background(0);

  randText=lines[frameCount].toUpperCase();

  for (int k=0; k<randText.length(); k++) {
    if (str(randText.charAt(k)).equals(" ")==true) {
      //randText.charAt(k)=; here i want to go to the next line
    }
  }
  text(randText, 10, frameCount*12);
}

```

thank you in advance!!

ok…i’ve found this method StringBuffer, but now i want decide if a specific character have be to changed or not.  
is there a way to do it?

```auto
String[] lines; 
String randText;
StringBuffer sb;

void setup() {
  size(1280, 720);
  lines = loadStrings("howl.txt");
  //ArrayList<StringBuffer> sb = new ArrayList<StringBuffer>();
  sb = new StringBuffer(lines.length);
  for (int i=0; i<lines.length; i++) {
    sb.append(lines[i]);
  }
  background(0);
  frameRate(1);
  noLoop();
}

void draw() {
  randText=sb.toString();
  randText=randText.replace(' ', '\n');
  text(randText, 10, frameCount*12);
}

```

for example i want to change just the second and fourth character " " not everyone, is it possible?

Yes with insert() method :

```auto
sb.insert(index,"your text to add")

```

Take a look : [https://docs.oracle.com/javase/7/docs/api/java/lang/StringBuffer.html](https://docs.oracle.com/javase/7/docs/api/java/lang/StringBuffer.html)

It’s not a method, but a `class`: ☕

- [class / Reference / Processing.org](http://Processing.org/reference/class.html)
- [Docs.Oracle.com/en/java/javase/11/docs/api/java.base/java/lang/StringBuffer.html](http://Docs.Oracle.com/en/java/javase/11/docs/api/java.base/java/lang/StringBuffer.html)

But since Java 5, we shouldn’t use StringBuffer anymore! We use the faster StringBuilder `class` instead: 🏗

- [StringBuilder (Java SE 11 & JDK 11 )](http://Docs.Oracle.com/en/java/javase/11/docs/api/java.base/java/lang/StringBuilder.html)

Did you look at split () ?

Makes your string to an array!

Then you can for loop over it.

Also: text() is also available with 5 parameters, so you have automatically a line break. Nice.
