Convert int array to string array
May 2^nd, 2010, 9:28am

Hi, I'm trying to debug my program which has columns which increase everytime the mouse is pressed in a range of the x-axis.

The program works until this part:

Code:


/* global integers */
int NumCols = 10;
int[] ColHs = new int [NumCols];
...
/* main program etc */
...
void keyPressed() {
  int i;
  String[] Array_of_String = new String[NumCols];
  for (i = 0; i < NumCols; i++) {
    Array_of_String[i] = ColHs[i];
  }
  saveStrings("IP.csv", Array_of_String);
}

I'm getting a "cannot convert int to string" error and i'm not sure why or how to fix this Sad

If anyone could point me in the right direction that'd be great! Cool

THANKS!!!! Exactly what i was looking for!

What did you mean by "it even does the loop for you"?

my code now:

Code:

/* global integers */
int NumCols = 10;
int[] ColHs = new int [NumCols];
...
/* main program etc */
...
void keyPressed() {
  int i;
  String[] Array_of_String = new String[NumCols];
  for (i = 0; i < NumCols; i++) {
    Array_of_String[i] = str(ColHs[i]);
  }   
/* added str() to ColHs[i]) */

  saveStrings("IP.csv", Array_of_String);
}

How would i be able to replace the "for loop" ?

It works great now, thanks for the pointer
