Java class: Food.java:

private int info[];
private String name;
public int num;
Food(String name,int []info) {
this.name = name;
this.info = info;
}
public String getFoodName(){

public String toString() {
String result = name +"\n"+"cal: "+ info[0]+"\n"+
"fat: "+info[1]+ "\n" + "chol: "+ info[2] +"\n"+"sod: " + info[3] +"\n" +
"prot: "+ info[4];
return result;
}
}
The database I read text from looks like this:
ham
90
90
49
20
10
ham
102
402
405
304
30
ham
90
48
80
59
40
When you type "ham" and press "search" and press "ham" and "search" then I get this error:
Apr 13, 2012 10:45:52 AM controlP5.ControlBroadcaster printMethodError
SEVERE: An error occured while forwarding a Controller value
to a method in your program. Please check your code for any
possible errors that might occur in this method .
e.g. check for casting errors, possible nullpointers, array overflows ... .
method: search
exception: java.lang.reflect.InvocationTargetException
Also if I search"ham" and search"corn", it gives that error too.
Please Help!
