This is the second solution to find the length of a given primitive int data type value. This approach converts int value to string, and then applies 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);
		
		// Convert Integer to String, and then use the length() function
		String int2Str=String.valueOf(numValue);
		System.out.println("The Length of the give num "+numValue+" is="+int2Str.length());		
	}
}
Try it >>
Output: 
 Enter an Integer=
 324
 The integer is=324
 The Length of an Integer 324 is=3
