can we use any other word than pionts in the code { in the text }

Question

import java.util.HashMap;
public class MyClass {
public static void main(String[ ] args) {
HashMap<String, Integer> points = new HashMap<String, Integer>();
points.put("Amy", 154);
points.put("Dave", 42);
points.put("Rob", 733);
System.out.println(points.get("Dave"));
}
}
// Outputs 42

Answer 1

Yes, points in this code is a variable identifier name. Variable names can be whatever you want within the allowable naming rules. see naming section here https://docs.oracle.com/javase/tutorial/java/nutsandbolts/variables.html

So, for instance you could change points to score.
