Answer 2

If you just want to convert the Double to int,

Double D = 45.56;
int i = Integer.valueOf(D.intValue());
//here i becomes 45

But if you want to remove all decimal numbers and count the whole value,

//first convert the Double to String 
double D = 45.56;
String s = String.valueOf(D);
// remove all . (dots) from the String
String str = str.replace(".", "");
//Convert the string back to int
int i = Integer.parseInt(str);
// here i becomes 4556

Answer 3

You are using the Double as object(Wrapper for type double). You need to fist convert it in to string and then int.

Double d=4.5;
int  i = Integer.parseInt(d.toString());

If you want it in the Integer Object Wrapper then can be written as

Integer  i = Integer.parseInt(d.toString());

EDIT If you want to get the desired result - You can go like this-

    Double d = 4.5;
    double tempD = d;
    int tempI = (int) tempD * 100;
    //Integer i = tempI;
