Question

I like how Groovy makes all of your instance variables and class variables public and writes getters and setters on your behalf. This saves a lot of unnecessary coding. On the other hand, my boss hates it, making me very sad 🙁

Is there a way to achieve the conciseness of Groovy in Java without having to use Groovy or some other framework/add-on?

I have a feeling the powers that be will not take kindly to the introduction of this foreign framework where I work.

So what I’m looking for is a solution to the excessive verboseness of Java without using Groovy or something like it.

Can it be done in Java alone – such as by simply making everything public?

Go with immutable datastructures. No getters, no setters, no hassle.

You may want to give Functional Java a try. It’s just a regular Java library, but comes with powerful abstractions and useful (immutable) datastructures that let you say more in less code. For example, translate this:

List<String> s = new ArrayList<String>();   for (String x : xs) {     for (String y : ys) {       for (String z : zs) {         s.add(doSomething(x, y, z));       }     }   } 

… to this:

List<String> s = xs.bind(ys, zs, doSomething);
