Here I have a program which creates a HashMap within a method
JavaScript
x
import java.util.HashMap;
class Evan {
public HashMap<String,Double> abilities_get() {
HashMap<String,Double> abilities = new HashMap<String,Double>();
abilities.put("stealth", 1.5);
abilities.put("strength", 1.2);
abilities.put("accuracy", 1.0);
abilities.put("intelligence", 2.0);
return abilities;
}
}
public class Main {
public static void main(String[] args) {
Evan evan = new Evan();
evan.abilities_get();
abilities.get("stealth");
}
}
This program doesn’t work due to the fact that in the main method “abilities” cannot be found. How can I make it so I can use my HashMap in the main function.

JavaScript
class Evan {
public HashMap<String,Double> abilities_get() {
HashMap<String,Double> abilities = new HashMap<String,Double>();
abilities.put("stealth", 1.5);
abilities.put("strength", 1.2);
abilities.put("accuracy", 1.0);
abilities.put("intelligence", 2.0);
return abilities;
}
}
class Main {
public static void main(String[] args) {
Evan evan = new Evan();
evan.abilities_get();
Double stealth = evan.abilities_get().get("stealth");
System.out.println(stealth);
}
}
Try it out
