Which method or action within an object will be executed first when it is called?

When calling an object's get() method, the constructor of that object is executed first — it initializes the instance state. If the object is already created, then the method itself is executed.

If we consider the order of method calls inside the object, the first executed method is the one called from outside. In inheritance cases, if a method overridden in a subclass is called, the subclass's version is executed.

Example:

public class Example {
    public Example() {
        System.out.println("Constructor");
    }
    public void method() {
        System.out.println("Method");
    }
}

// When creating an object:
Example ex = new Example(); // Prints "Constructor"
ex.method(); // Prints "Method"
