How to read the decimal portion of a double number? (using scanner method)

Question

hello Java pros....
I need to read the integer and decimal part of a double number, one independently of the other.
I must be able to assign the integer part to a variable, and the decimal part to a different variable.
Is there a method that does what I need directly after reading the initial value (double) ?
or, should I include the condition to read the decimal point somehow?
the initial value will be input from the console using a scanner method.
lets say the number I have is 123.345
I must be able to separate 123 from 345 and use them independently.
thank you all!!

The scanner should read in the user input as a string, so you have "123.456". Do something like the following:
String   doubleNumber             = "123.456";
String[] numberParts              = doubleNumber.split("\\.");
int       wholeNumberPortion       = Integer.parseInt(numberParts[0]);
int       fractionalPortion        = Integer.parseInt(numberParts[1]);
System.out.println(wholeNumberPortion  + "." +  fractionalPortion);
