As a beginner in programming and learning Processing,I am really stuck on this. Probably as simple as it can be but I don't see it anymore. What am I doing wrong?
int geefCijfer (int[] cijfer1) {
String [] cijfers =loadStrings("cijfers_klein.txt");
int [] cijfer = new int [cijfers.length];
for (int i = 0; i< cijfers.length; i++) {
cijfer[i] = int(cijfers[i]);
println(cijfer);
}
return cijfer;
}
In the future, please try to be more specific. Include in your question what you expect the code to do, what it does instead, and a MCVE that demonstrates the problem.
That being said, I copied your code into my Processing editor and I get a compiler error on this line:
return cijfer;
The error says:
Type mismatch: cannot convert from int[] to int
This is happening because you're returning cijfer, which is an int[] type, but you've declared your function to return an int. You either need to change what you're returning, or change the return type of the function. My guess is you just want to change the return type:
int[] geefCijfer (int[] cijfer1) {
This gets rid of the error, but you'll still have a warning because you never use the cijfer1 variable. That won't prevent you from running your code, but it's probably something you want to think harder about.
Also note that instead of manually converting each index of the array, you can pass the whole array into the int() function:
String [] cijfers =loadStrings("cijfers_klein.txt");
int [] cijfer = int(cijfers);
