I'm attempting to save an "x" amount of integers inside of an object class. I'm trying it via an array but am not sure if this is possible and as of now eclipse is giving me two errors. One asking me to insert an Assignment operator inside of my Gerbil() class and another saying that I can't make a static reference to to the non-static field "food." The result I'm looking for is food 1 = first input; food 2 = second input; until it hits the total amount of food.

Here's my code so far:

import java.util.Scanner;
public class Gerbil {

public String name;
public String id;
public String bite;
public String escape;
public int[] food;

public Gerbil() {
  this.name = "";
  this.id = "";
  this.bite = "";
  this.escape = "";
  this.food[]; // I'm not sure what I should put here. This is where I want to store
}              // the different integers I get from the for loop based on the
               // total number of foods entered. So if totalFoods is 3, there should
               // be 3 integers saved inside of the object class based on what's typed
               // inside of the for-loop. Or if totalFoods = 5, then 5 integers.

public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
System.out.println("How many foods?");
int totalFood = keyboard.nextInt();

System.out.println("How many gerbils in the lab?");

int numberOfGerbils = keyboard.nextInt();
Gerbil[] GerbilArray = new Gerbil[numberOfGerbils];

for(int i = 0; i <= numberOfGerbils; i++){
    GerbilArray[i] = new Gerbil();

    System.out.print("Lab ID:");
    String id = keyboard.next();

    System.out.print("Gerbil Nickname:");
    String name = keyboard.next();

    System.out.print("Bite?");
    String bite = keyboard.next();

    System.out.print("Escapes?");
    String city = keyboard.nextLine();

    for (int j = 0; j < totalFood; j++) {
        System.out.println("How many of food " + (j+1) + "do you eat?:");
        food[j] = keyboard.nextInt();
    }

}
}
}

food[j] = keyboard.nextInt();. Whose food is this? –  Karolis Juodelė Apr 19 at 4:00
    
food[j] is gerbilArray[i]'s food. I want it to run for j = total number of food. But I want it to do be able to save each specific food, and do this for each gerbil. So gerbilArray[i+1] will be asked the same, and can save different numbers for each food food[j]. –  newJavaUser Apr 19 at 4:12
    
It's because of the i <= numberOfGerbils. It should just be i < numberOfGerbils –  Simon Corcos Apr 19 at 4:27
    
Just because you found an answer, does not mean you should clear out the question and tell us that it must be deleted. –  Takendarkk Apr 20 at 23:09

You need to pass the number of food in the Gerbil constructor :

public Gerbil(int totalFood) {
   this.name = "";
   this.id = "";
   this.bite = "";
   this.escape = "";
   this.food[] = new int[totalFood]; 
}

And then in the loop will look like this :

for(int i = 0; i <= numberOfGerbils; i++){
GerbilArray[i] = new Gerbil(totalOfFood);

System.out.print("Lab ID:");
String id = keyboard.next();

System.out.print("Gerbil Nickname:");
String name = keyboard.next();

System.out.print("Bite?");
String bite = keyboard.next();

System.out.print("Escapes?");
String city = keyboard.nextLine();

for (int j = 0; j < totalFood; j++) {
    System.out.println("How many of food " + (j+1) + "do you eat?:");
    GerbilArray[i].food[j] = keyboard.nextInt();
}

}

Or something like that should do it.
