How to know if the bean has got some values or not

Suppose there is some bean named employee:

and has many fields like first name, last name, emp no, age , addr, designation etc.

Is there a way by which I can test if none of the fields have been set?.

I mean, I get a reference through which I can get all values one by one and check if all are empty/null. but is there a better way to find if none of the fields have been set in the bean

Yes, you can do it exactly like you are thinking... there is no Out of the Box method for that, but you can create a method that return a boolean and this represent the state of the Bean you want to check...

Example:

public boolean isProperlyInitialized(){
     boolean condition1 = age!=0;
     boolean condition2 = ...;

     return condition1 && condition2 &&....;
}

and implemented in the code

Bean b = new Bean();

if(b.isProperlyInitialized){
    //Do something cool
}
