This is the first solution to find the length of a given double value. This approach converts double value to string and uses the length method.

import java.util.Scanner;

public class LengthOfDoubleValue {

	public static void main(String[] args) {
		// TODO Auto-generated method stub

		@SuppressWarnings("resource")
		Scanner inpDouble= new Scanner(System.in);
		
		//Input an Integer
		System.out.println("Enter Double number=");
		double doubleNum=inpDouble.nextDouble();
		System.out.println("The Double value is="+doubleNum);
		
		// Convert Double number into a String and use the length function		
		String[] dblToStr=String.valueOf(doubleNum).split("\\.");
		System.out.println("The Length of the given float number "+doubleNum+" before . is="+dblToStr[0].length());
		System.out.println("The Length of the given float number "+doubleNum+" after . is="+dblToStr[1].length());
	}
}
Try it >>
Output:
 Enter Double number=
 34353.3233
 The Double value is=34353.3233
 The Length of the given Double number 34353.3233 before . is=5
 The Length of the given Double number 34353.3233 after . is=4
