Figuring out whether a number is a Double in Java

Question

Can anyone help me how I can able to figure it out that a number is double or not? I am using this syntax:

if ( typeof ( items.elementAt(1) )== Double ) {

       sum.add( i, items.elementAt(1));

}

How can I make it work properly?

Answer 1

You can try with this code:

if (items.elementAt(1) instanceof Double) {

   sum.add( i, items.elementAt(1));

}

I hope this will help.
