WITH statement in Java

In VB.NET there is the WITH command that lets you omit an object name and only access the methods and properties needed. For example:

With foo
   .bar()
   .reset(true)
   myVar = .getName()
End With

Is there any such syntax within Java?

Thanks!

If you have hands on the implementation of Foo, you can use the fluent API concept.

Lets say you have that:

public class Foo {
    private String a;
    private String b;
    public void setA(String a) { this.a = a; }
    public void setB(String b) { this.b = b; }
    public String getName() { return this.a + " " + this.b; }
}

Then you could modify it to obtain this:

public class Foo {
    private String a;
    private String b;
    public Foo setA(String a) { this.a = a; return this; }
    public Foo setB(String b) { this.b = b; return this; }
    public String getName() { return this.a + " " + this.b; }
}

And your calling code could look like:

String name = new Foo().setA("foo")
                       .setB("bar")
                       .getName();

Enjoy!
