This is the third solution to find the length of a given primitive int data type value. This approach uses Integer wrapper class to convert to string before using the length method.

import java.util.Scanner;

public class LengthOfPrimitiveInt {

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

		@SuppressWarnings("resource")
		Scanner inpInt= new Scanner(System.in);
		
		//Input an Integer
		System.out.println("Enter an Integer=");
		int numValue=inpInt.nextInt();
		System.out.println("The integer is="+numValue);
		
		// Use the Wrapper class of an int i.e. Integer to find out the length
		System.out.println("The Length of the given num "+numValue+" is="+Integer.toString(numValue).length());		
	}
}
Try it >>
Output:
 Enter an Integer=
 324
 The integer is=324
 The Length of an Integer 324 is=3
