import java.util.Scanner; // this program will let you know the area of your cuboid public class Nexus { public static void main(String[]args) { Scanner dc = new Scanner(System.in) ; Scanner ac = new Scanner(System.in) ; Scanner xc = new Scanner(System.in) ; double length = dc.nextDouble(); double breadth= ac.nextDouble(); double height = xc.nextDouble(); double area = length*height*breadth; System.out.println(area); } }

I'd say that you don't need 3 scanners, just one (for example, "dc" --then remove ac and xc declarations), and in that one scanner, get nextDouble() three times, one for each dimension of your cuboid.
[EDIT] An input scanner is a data flow that waits for data to be typed (or input via a file, for instance). You normally need one input scanner, then you keep on getting nextDouble, nextChar or whatever, until the data flow comes to an end (of file).

Try removing the extra scanners, they aren't single-use items. Keep calling nextDouble() from dc, remove ac and xc, report again if it still isn't working.
