Tuan Dang

Hi,

I am Tuan, a student.
I currently learn Java, and doing certifications along the side. (I got my OCAJP and OCPJP)
My next path is to learn about Spirng(Spring Professional 5.0 Certification) or Java EE (Java EE 7 Application Developer | 1Z0-900)
I did some research about Java and Spring, I see almost everyone is talking about Spring today.
I want to learn both but I also want to have job within the next year.
I try to build my profolio and bug tracker website from scratch with one of these two technology while learning to solid my knowledge.

I have two questions:
    1. Is Java EE still used today and is it worth it to learn it. For job security which path should I choose: Spring or Java EE ?
    2. I have one year, is it possible to do learn both Java EE and Spring, and got both certifications in one year ?

Thanks for your attention. I’m looking forward to your reply.

Thank you for clarifying!

Hi,

Can you explain me more clearly what type of object is byName is ? And where should i find the information about this type (or operation)  in Java SE 8 Doc .
System.out.println(byName.getClass()) result is class DuckHelper$$Lambda$1/990368553

Code below:

// Duck class
public class Duck implements Comparable<Duck> {    private String name;    private int weight;    public Duck(String name, int weight) {        this.name = name;        this.weight = weight;    }    public String getName()  { return name; }    public int getWeight() { return weight; }    public String toString() { return name; } }

// DuckHelper class:
import java.util.Comparator; public class DuckHelper {    public static int compareByWeight(Duck d1, Duck d2) {        return d1.getWeight() - d2.getWeight();    }    public static int compareByName(Duck d1, Duck d2) {        return d1.getName().compareTo(d2.getName());    }    public static void main(String[] args) {        Comparator<Duck> byName = DuckHelper::compareByWeight;        System.out.println(byWeight.getClass());   // The result is:  class DuckHelper$$Lambda$1/990368553    } }

Thank you for your help
