Program to check lead number in java

In this section, you will learn how you can easily check the lead number by using Java program.

What is Lead Number?

It is a number in which the sum of even digits is equal to the sum of the odd digits or vice-versa, Let's see:

For example : 6325

• Sum of even number : 6 + 2 = 8

• Sum of add number : 3 + 5 = 8

Here, the Sum of even number is equal to the sum of the odd digits, So 6325 is a lead number.

Let's try to create a simple program :

  ➤ Code : LeadNumber.java;

import java.util.*;
class LeadNumber{
   public static void main(String args[]){	
      Scanner input=new Scanner(System.in);
      System.out.print("Enter a number to check the number is Lead Number : ");        
      
      int number = input.nextInt();	// 6325 
      int r=0,odd=0,even=0;
      while(number>0)
      {
         r=number%10;	//5,2,3,6 
         if(r%2==0){
            even=even+r;	//2+6 = 8
         }
         else{
            odd=odd+r;	// 3 + 5 = 8
         }
         number = number/10;
     }
     if(odd==even)
        System.out.println("This is a Lead Number");
     else
        System.out.println("This is not a Lead Number");
   }
}

Output :

Enter a number to check the number is Lead Number : 6325

This is a Lead Number
