      Non static variable

      Can someone pls help ? How do I get my global variables destinationCity Code, numberOfAdults and isReturn to be populated with values from the user ?
      I will need them for calculations in to be passed to other methods later. Thanks in advance... pls help.

      Code:
      import java.util.*;
import java.text.*;
import java.math.*;
import java.io.*;          // Access System.out
 
public class MyBooking
      ...

        I did indeed figure it out by testing. :)


        System.out.prin tln("Lastly, enter Number of Hours.");
        numberOfHours = Math.ceil(in.ne xtDouble());
        intHours = (int)numberOfHo urs;

        Because we had to accept a double, I converted the ceiling value to an int.

          I'm pretty sure the ceiling() method is my answer. Any hints? :)

            I'm sorry. I have indeed confused the class with the package.

            However, i am still unsure how to find the nearest higher integer when a float is
            passed into the function.

            I'm still new to java, so i'll have to re-look the methods. :(

              I'd like to believe that the java.math API could actually assist, and have been experimenting with the nextUp() and round() methods. However, each time i try to use one of these, i get a method - class not found error in my script.

              i HAVE imported java.math.* previously at the start of the code.

              What are the probable causes of method - class not found? I am on 1.6 by the way.

                Hi there!

                Thanks for the reply, however, could anyone be kind enough to provide the actual code to complete the following :

                float x;
                x = 3.1417;

                //syntax to round float x upwards to 4
                x = ......

                Thanks fellas.

                  Rounding up a float value

                  Hi everyone,

                  I'd like some help to round UP a float value to the nearest higher integer.
                  This means,

                  1.2 will be rounded up to 2
                  2.15 will be rounded up to 3
                  4.01 will be rounded up to 5
                  9.47 will be rounded up to 10 etc etc

                  I think the functions to use lie somewhere in the math class, but i'm not sure how to manipulate the methods available therein.

                  Please...
