no, you cannot do this.
instead, use a lookup table of strings, and use the prediction / label value as index, maybe like this:
String lut [] = {"apples", "pears", "oranges"};
int predicted = knn.findNearest( testData, 3);
String fruit = lut[predicted];
(btw, you should use integer labels for KNearest, not float)
