Anonymous Objects in Java

Java helps us creating anonymous object using

new class_name();

statement and calling the methods using association(.) operator like

new Emp().input();

How can I use it to invoke two methods simultaneously from an anonymous object like invoking both input() and show() together ?

public Emp show() {
    // do the stuff
    return this;
}
public Emp input() {
    // do the stuff
    return this;
}

Then call with

new Emp().show().input();

What you can also do, without modifying the Emp class, is create an anonymous class that extends your class to allow it to call both methods.

new Emp() {
    public void doStuff() {
        input();
        show();
    }
}.doStuff();

Which as a bonus gives you an anonymous instance of an anonymous class.

How about making a method:

public void inputThenShow() {
    input();
    show();
}

Then call with

new Emp().inputThenShow();
