This is the second solution to find the length of a given float value. This approach uses Float wrapper class to convert to string before using the length method.

import java.util.Scanner;

public class LengthOfFloatValue {

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

		@SuppressWarnings("resource")
		Scanner inpFloat= new Scanner(System.in);
		
		//Input an Integer
		System.out.println("Enter Float number=");
		float floatNum=inpFloat.nextFloat();
		System.out.println("The Float value is="+floatNum);
				
		// Use the Wrapper class of an decimal i.e. Float to find out the length
		String[] fltToStr=Float.toString(floatNum).split("\\.");
		System.out.println("The Length of the given float number "+floatNum+" before . is="+fltToStr[0].length());
		System.out.println("The Length of the given float number "+floatNum+" after . is="+fltToStr[1].length());
		}
}
Try it >>

Output:  
 Enter Float number=
 34.212
 The Float value is=34.212
 The Length of the given float number 34.212 before . is=2
 The Length of the given float number 34.212 after . is=3
