How to convert a list with properties to a another list the java 8 way?
<p>There is a List A with property Developer. Developer schema likes that:</p>

<pre><code>@Getter
@Setter
public class Developer {
    private String name;
    private int age;

    public Developer(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public Developer name(String name) {
        this.name = name;
        return this;
    }

    public Developer name(int age) {
        this.age = age;
        return this;
    }
}
</code></pre>

<p>List A with properties:</p>

<pre><code>List&lt;Developer&gt; A = ImmutableList.of(new Developer("Ivan", 25), new Developer("Curry", 28));
</code></pre>

<p>It is demanded to convert List A to List B which with property ProductManager and the properties is same as the ones of List A.</p>

<pre><code>@Getter
@Setter
public class ProductManager {
    private String name;
    private int age;

    public ProductManager(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public ProductManager name(String name) {
        this.name = name;
        return this;
    }

    public ProductManager name(int age) {
        this.age = age;
        return this;
    }
}
</code></pre>

<p>In the old days, we would write codes like:</p>

<pre><code>public List&lt;ProductManager&gt; convert() {
    List&lt;ProductManager&gt; pros = new ArrayList&lt;&gt;();
    for (Developer dev: A) {
        ProductManager manager = new ProductManager();
        manager.setName(dev.getName());
        manager.setAge(dev.getAge());
        pros.add(manager);
    }
    return pros;
}
</code></pre>

<p>How could we write the above in a more elegant and brief manner with Java 8?</p>
