HI Friends,
I wrote a class like as follows.

Class A() {
void add(String a,String b) {
System.out.println("add method with strings");
}

void add(Date d1,Date d2) {
System.out.println("add method with dates");
}

}

If I call above add method with parameter values as "null" like as follows, then what will be the output?

add(null,null);

It will throws any exception or displays any message?

please answer this .

Best way to find out is, try it your self. Then you can experiment in different ways as well.

I think while compiling itself it will give message
ambigious
etc,as null value is applicable both for String and Date .how will compiler know which add?both have null as valid parameters.
