Food.java code:
public class Food {
private int info[];
private String name;
public int num;
Food(String name,int []info) {
this.name = name;
this.info = info;
}
public String getFoodName(){
return name;
}
public void setFoodName(String name){
this.name = name;
}
public int[] getInfo(){
return info;
}
public void setInfo(int[] info){
this.info = info;
}
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;
}
}
This is my code and the text file that works as a database looks like this:
ham
20
10
20
40
50
ham
20
10
20
40
50
ham
20
10
20
40
50
I am having an error if I put "ham" in the textfield and press "Search" many times.
Also, I am having an error when I put "ham" and press "Search" and later put "corn" and press "Search".
I am having an error on addItems methods, but I don't know why....
My console says:
Apr 13, 2012 10:45:52 AM controlP5.ControlBroadcaster printMethodError
