call chaining

[vlad]

What is the problem here..? Why doesn't this work?

public class Foo2 {
String a = "he";

String test1(){return a + "ll";}
String test2(){return "oo";}
String test3(){return "ow";}
}
public class Foo{

public static void main(String[] args) {

Foo2 foo = new Foo2();

String a = foo.test1().test2().test3();
System.out.println(a);

}

}

Because test2 and test3 are not methods of String, and a String is what test1 and test2 return.

Thanks msijade! I am just trying to test some method chaining ideas... So the first test1() and second test2() both return a reference to a String and thats why its not working... So how would you convert it so it would return Foo2 type instead..? thnx! - vlad
