java practical 3 (Given two non-negative int values, return true if they have the same first digit, such as with 72 and 75. firstDigit(7, 71) → true firstDigit(6, 17) → false firstDigit(31, 311) → true )

 

AIM: Given two non-negative int values, return true if they have the same first digit, such as with 72 and 75.
firstDigit(7, 71) → true   firstDigit(6, 17) → false
firstDigit(31, 311) → true

code :

import java.util.*;

class Cal{

    static boolean firstDigit(int a, int b)

    {

        while(a>=10)

            a/=10;

        while(b>=10)

            b/=10;

        if(a==b)

            return true;

        else

            return false;

    }

}

public class Three {

    public static void main(String[] args) {

        int a,b;

        char response='n';

        Scanner in=new Scanner(System.in);

        do{

            System.out.print("Enter Two Digits: ");

            a=in.nextInt();

            b=in.nextInt();

            boolean ans=Calculation.firstDigit(a,b);

            System.out.println("Answer:"+ans);

            System.out.println("If You want to continue press (y) ,else press (n)");

            response=in.next().charAt(0);

        }while(response=='y');

        System.out.println("\nPrepared By: 19CE112 PIPARIYA PREYASH");

    }
