Code:



    if (lines[d] = 2) {  <<<this part have a problem he said (is not assignable)

Lines are of type String. You want lines[d].equals("2") or something similar.

Code:


 if (d =2)

d = 2 is not a comparison. You'll want d==2.

thanks you again

I want

Code:
If (lines[d].equals("2")) {
ellipse(200, 200, 40, 40);
}

but it show up at start

this is my original code
Code:
String lines[] = loadStrings("/data/time.txt");
//println("there are " + lines.length + " lines");
//println(lines);
for (int i=0; i < lines.length; i++) {
//println(lines[i]);
//String str1 = lines[i];
//println(str1);
if (lines[i].equals("2.0")) {
ellipse(20, 20, 40, 40);
}
}

I changed the code and it works

String lines[] = loadStrings("/data/time.txt");
//println("there are " + lines.length + " lines");
//println(lines);
for (int i=0; i < lines.length; i++) {
//println(lines[i]);
//String str1 = lines[i];
//println(str1);
if (lines[i].equals("2.0") == true) {
ellipse(50, 50, 10, i);
}
}

And
If I run the saving file A and Loading file B at same time
file B won't happen anything

It only works if i run file A and close it then run file B

I need to reflesh the txt on time
and read it on time
