An instance is defined by the class, method, or conditional statement. Scope is what is between the two curly braces. Class variables are variables defined in the scope, and instance variables are those defined in the class, method, or conditional statement. For example:

public class InstanceExample { //This is a class instance, and everything in this instance is between the curly braces.
    //class variables go here.
    public InstanceExample() {
      // constructor code goes here
   }

    public void printHello() {
        String message = "Hello"; // This is an instance variable, defined within the method.
    }
}

Hope this helps!

Thanks,

Zac
