This might help you What you're referring to is called chaining. Aside from the fact that delay is used for animations, the key point to remember is to return this from your function.
If you'd like to see how specific jQuery functions work, check out the code for removeClass:

Hope that helps If you invoke A.doSomething() it will just execute that static method. Saying a's doSomething does not make sense because static methods do not belong to an object or instance of your class.

hope this fix your issue I have a button that adds to a panel that adds to a frame. Now when I click this button I want it to call the method eat() which is a method of the Lion class. Now how would I do this with out containing the new object within the mousePressed method the below creates a new instance of the object each time it's clicked. I only want one instance of the object and to call the method on that instance how do I do this? , Define the object as member attribute of the class:
code :
final Lion adam = new Lion("Adam");
public void clickMe(){
btnOpenNewFile.addMouseListener(new MouseAdapter() {
        public void mousePressed(MouseEvent e) {

            Cat meo = new Cat("Meo");
            adam.eat(meo);


        }
    });
}

With these it helps Don't give the self invoking function a name (there is little benefit to it beyond making it easier to find in a stacktrace, which you shouldn't need at that point, and it memory leaks in old IE) Don't call the self invoking function twice Don't treat the self invoking function as if it was a constructor function (by calling it with new) Do capture the return value of the self-invoking function
Such:
code :
    var x = (function () {
        var j = function() { alert("234234"); };
        return {
            s: j
        };
    })();
    
    x.s();
    function x () {
        var j = function() { alert("234234"); };
        return {
            s: j
        };
    };

    var x1 = x();
    var x2 = x();
    x1.s();
    function x () {
    };

    x.prototype.s = function () {
        alert("234234");
    }
    
    var x1 = new x();
    var x2 = new x();
    x1.s();

this will help I have 2 classes. Is it possible to set gui object's switchingPanel variable, using gui's setSwitchingPanel method? I know i can't invoke this method from other class in easy way. Is there any way to invoke this metod in AddPatientPanel.class without making JPanels variables and this method as static? I am a beginner, but I have read to avoid anything static. , To call a method from another class, you have three options:
code :
GUI gui = new GUI();
gui.setSetSwitchingPanel();
public class AddPatientPanel extends JPanel
{
    private GUI gui;

    public AddPatientPanel(GUI gui)
    {
        this.gui = gui;
    }

    public void myMethod()
    {
        gui.setSwitchingPanel(JPanel panel2) 
    }
}

I wish did fix the issue. In the story.xml file your TextView has id textView2 but in the java code you are finding that view using id textview. Make sure you use the same id at both places.
code :
t = (TextView) this.findViewById(R.id.textview);
